6.3.1 Description
The intention of the electrical service diagnostics is to show the software versions present in the player and to direct the dealer towards defective internal units. The units are : the CDR main board, the CDR loader, the CD loader in case of a CDR500 and the keyboard/display board. A sequence of tests is executed automatically. Some of the tests can be aborted or skipped without the result being taken into account. External tools or disassembly of the unit is not necessary to get the diagnostic information. Pressing keys [PLAY/PAUSE] and [F FWD] simultaneously while switching on the unit, starts the test. Switching off the unit ends the test.
6.3.2 Requirements to perform the test
Working keyboard to start up the test. Working local display to check the output messages. A CD-DA disc with a minimum of 3 tracks in all trays to
perform the disc test.
6.3.3 Description of the tests
Player informationIn this part of the test the following important information can be checked without removing the cover : Recorder ID. SW-version back end of player. SW-version CDR loader. SW-version CD loader (only for CDR500).
CDR main board test[F FWD] key. The message "DERRn" will be displayed with n indicating the faulty test number.If one of the tests is aborted with the [F FWD] key, no error message will be displayed for this test. The flash data erase test ("DTST3") can not be aborted !The CDR main board test consists out of :
DRAM test Display : "DTST1". The DRAM used for buffer management is tested by writing, reading and verifying test patterns.
Flash checksum testDisplay : "DTST2". This test checks the checksum of the player's SW stored in the flash.
Flash data eraseDisplay : "DTST3". During this test, all temporary information (CDtxt) in the flash is erased.
CODEC (ADC/DAC) testDisplay : "DTST4". This test checks the CODEC IC by writing, reading and verifying test patterns. The test is not applicable for CDR950.
CDR communication testDisplay : "DTST5". The communication between the host processor (DASP) and the CDR loader via the DSA-R-bus is tested.
CD communication testDisplay : "DTST6"). The communication between the host processor (DASP) and the CD loader is tested. The test is only applicable for CDR500.
Loader testsThese tests determine if the CDR loader and the CD loader in case of a CDR500 work correctly. A CD-DA disc with a minimum of 3 tracks needs to be inserted in both loaders. A
disc test is executed to check focus control, disc motor control, radial control and jump grooves control. The disc test is performed by audio play-back of 5 seconds at the beginning, middle and end of the disc.
CDR loader testDuring the test, the current disc time is shown. In case of an error the message "BERR1" will be displayed and the [F FWD] key must be pressed to continue with the following test. Pressing the [F FWD] key also aborts this test.
CD loader testFor CDR500 only. During the test, the current disc time is shown. In case of an error the message "BERR2" will be displayed and the [F FWD] key must be pressed to continue with the following test. Pressing the [F FWD] key also aborts this test.
Display testAll segments will blink at a frequency of 1 Hz. Pressing the [F FWD] key will start the next test because the user has to check for himself if all segments work properly.
Keyboard and remote control testsThe test will give the user the ability to test every key without executing the function assigned to it. Therefore, the user needs to press every key on the keyboard and the remote control. The display will show the name of the key being pressed. Pressing more than one key at once will give an unpredictable result except for the service combinations : [PLAY/PAUSE] + [STOP], [PLAY/PAUSE] + [F FWD], [F FWD] + [REWIND], [ERASE] + [RECORD], [PLAY/PAUSE] + [RECORD].
6.4 Mechanical service diagnostics
Figure 6-3
6.4.1 Description
No external tools are required to perform this test. The cover needs to be removed because the user has to check the movements of the tray, focus and sledge visually. Pressing keys [PLAY/PAUSE] and [STOP] simultaneously while switching on the unit, starts the test. Switching off the unit ends the test. In case of a CDR500, one can check the CD loader mechanics in the same way by pressing the above key combination on the CD player keys.

Tray control testThis test starts from within the focus control test routine. Pressing [OPEN/CLOSE] moves the tray in or out. In the tray open position one can initiate focus and sledge tests by pressing [F FWD]. One has to stop these tests pressing [REWIND] before it is possible to close the tray again. Depending on the action the display reads "OPEN", "OPENED", "CLOSE" or "BUSY".
6.5 DC-erase service mode
Figure 6-4
6.5.1 Description
This test is initiated by pressing [ERASE] and [RECORD] simultaneously while switching on the unit. The player will erase a complete CD-RW disc (including PMA and ATIP lead out area) at speed N=2. The display shows the countdown of the remaining time required for the operation to complete. The format is "ER mm:ss", where "mm" are the remaining minutes and "ss" the remaining seconds. After completion the message "PASSED" is shown, and the player has to be switched off and on again to start up in normal operating mode. Switching off the unit before completion of the test, leaves the disc in an unpredictable state. In such case only a complete DC-erase procedure can recover the CD-RW disc.

8.1 Display Board
8.1.1 Description of display board
General descriptionThe display board has three major parts : the FTD (Fluorescent Tube Display), the display controller TMP87CH74F and the keyboard. The display controller is controlled by the DASP master processor on the CDR main board. The communication protocol used is I2C. So all the information between DASP and display controller goes via the SDA or I2C DATA and SCL or I2C CLK lines. Communication is always initiated by the DASP on the CDR main board. Unlike the previous generations of CDR players, the interrupt generated by the display controller at key-press or reception of remote control is not used. Instead, the DASP polls the display controller for these events.
Display controller TMP87C874FTMP87CH74F ( QY01) is a high speed and high performance 8-bit single chip microprocessor, containing 8-bit A/D conversion inputs and a VFT (Vacuum Fluorescent Tube) driver. In this application, its functions are : slave microprocessor. FTD driver. generates the square wave for the filament voltage
required for an AC FTD. generates the grid and segment scanning for the FTD. generates the scanning grid for the key matrix. input for remote control.All the communication runs via the serial bus interface I2C. The display controller uses an 8MHz resonator as clock driver.

8.1.2 Test instructions
Supply voltagesThe display board receives several voltages via connector JY01.• VFTD : -35V ±5% measured at pin 2 of conn. JY01.• VDC1-VDC2 : 4.1V ±10% measured between pin 1 and 3 of
conn. 1119.• +5V : +5V ±5% measured at pin 10 of conn. JY01
Voltages VFTD, VDC1 and VDC2 are produced in the power supply unit and sent to the display board via the CDR main board. The +5V voltage is produced on the CDR main board as D5V.
Clock signalAs clock driver for the display controller, a resonator of 8 MHz (XY01) is used. The signal can be measured at pins 8 and 9 of the display controller : 8 MHz ±5%.
Control signals
RESETThe reset signal comes via pin 4 of conn. JY01 from the DASP master processor on the CDR main board (SYS_RESET). The reset is low active. It should be kept low during power up for at least 3 machine cycles with supply voltage in operating range and a stable clock signal (1 machine cycle = 12 x 1/Fc (8 MHz) sec.). During normal operation, the reset should be high (3V3). The high signal is 3V3 because the DASP operates on 3V3.
I2C DATA/I2C CLKThese lines connect to the DASP master processor via respectively pin 5 and pin 7 of conn. JY01 . When there is no communication, they should have the high level (+5V). The oscillogram below gives an indication of how these signals should look like.
Figure 8-2 ‘I2C signals’
FTD drive lines
Filament voltageShould measure 4.1V ±10% (=VDC1-VDC2) between pins 1-3and pins 1-52 of the FTD(VX01).
Grid linesLevel and timing of all grid lines, G1-->G15, can be checked either at the FTD itself or at the display controller. Grid lines G13, G14 and G15 each have an extra current amplifier in line : QY04 for G13, QY03 for G14 and QY02 for G15. A typical grid line signal shows in the oscillogram below.
Figure 8-3 ‘Gridline’
Segment linesLevel and timing of all segment lines, P1-->P21, can be
checked either at the FTD itself or at the display controller.The data on these segment lines however, characters displayed. The oscillogram below shows asegment
line with data. A segment line without data
maintains a -34V level.
Figure 8-4 ‘Segment line’
Key matrix linesThe lines connected to pins 34, 35, 36 and 37 of the display controller act as matrix scanners. Without a key pressed, they maintain a low level. As soon as a key is pressed, the scanning line connected to that key puts out a scanning signal, which should look like the oscillogram below. This scanning signal goes via the pressed key to I/O port 4 of the display controller (pins 28 to 33). The display controller can now determine which key has been pressed. Without a key pressed, pins 28 to 33 of the display controller maintain a high level (+5V).

Easy jog knob
Rotary operationThe easy jog knob (SY26) incorporates a whole heap of user control possibilities in just one knob. Without the knob being operated, pin 1 and 3 of the knob (and thus pin 16 and 17 of the display controller), maintain the +5V level. Turning the knob clockwise briefly connects pin 1 to GND followed by pin 3.
Figure 8-6 ‘Turn clockwise’
Turning the knob anti-clockwise briefly connects pin 3 to GND followed by pin 1.
Figure 8-7 ‘Turn anti-clockwise’
The pulses created this way arrive at pin 16 and 17 of the display controller. The first pulse to arrive tells the controller the direction of the rotation. Counting the pulses reveals the amount of rotation. Combining and decoding this information, the display controller will execute the appropriate task.
Push button operationThis button connects to the key matrix lines and thus the operation is identical to the ordinary keys. Without being pressed, pin 4 of the easy jog maintains the low level, pin 5 the high level. When pressed the scanning signal goes through the closed contact of pins 4 and 5, and can be checked at both pins.
IR receiver - remote controlIn the CDR500 the IR receiver RPM6934-V4 (ZY01) is mounted on the IR board. In all versions the IR receiver connects to the display controller. The signal coming from the receiver can be checked at pin 22 of the display controller. This signal is normally high (+5V). When the remote control is being operated, pulses mixed in with the +5V can be measured. The oscillogram gives an indication of how the signal looks like with the RC being operated.

8.2 Power Supply Unit P816
8.2.1 Description of P816
MOSFET Q825 is used as a power switch controlled by the controller Q810. When the switch is closed, energy is transferred from mains to the transformer. This energy is supplied to the load when the switch is opened. Through control of the switch-on time, the energy transferred in each
cycle is regulated so that the output voltages are independent of load or input voltage variations. The controlling device MC44603 is an integrated pulse width modulator. A clock signal initiates power pulses at a fixed frequency. The termination of each output pulse occurs when a feedback signal of the inductor current reaches a threshold set by the error signal. In this way the error signal actually controls the peak inductor current on cycle-by-cycle basis.
Figure 8-10 ‘Blockdiagram P816’
Description of controller MC44603The MC44603 is an enhanced high performance controller that is specifically designed for off-line and DC-to-DC converter applications. This device has the unique ability of automatically changing operating modes if the converter output is overloaded, unloaded or shorted. The MC44603 has several distinguishing features when compared to conventional SMPS controllers. These features consist of a foldback facility for overload protection, a standby mode when the converter output is slightly loaded, a demagnetization detection for reduced switching stresses on transistor and diodes, and a high current totem pole output ideally suited for driving a power MOSFET. It can also be used for driving a bipolar transistor in low power converters. It is optimised to operate in discontinuous mode but can also operate in continuous mode. Its advanced design allows use in current mode or voltage mode control applications.

Pin Name Description
1 VCC This pin is the positive supply of the IC. The operating voltage range after start-up is 9.0 to 14.5 V.
2 VC The output high state (VOH) is set by the voltage applied to this pin.
3 Output Peak currents up to 750 mA can be sourced or sunk, suitable for driving either MOSFET or bipolar transistors.
4 Gnd The groundpin is a single return, typically connected back to the power source.
5 Foldback Input The foldback function provides overload protection.
6 OvervoltageProtection
When the overvoltage protection pin receives a voltage greater than 2.5V, the device is disabled and requires acomplete restart sequence.
7 Current SenseInput
A voltage proportional to the current flowing into the power switch is connected to this input.
8 DemagnetisationDetection
A voltage delivered by an auxiliary transformer winding provides to the demagnetisation pin an indication of themagnetisation state of the flyback transformer. A zero voltage detection corresponds to complete coresaturation.
9 SynchronisationInput
The synchronisation input pin can be activated with either a negative pulse going from a level between 0.7V and3.7V to Gnd or a positive pulse going from a level between 0.7V and 3.7V up to a level higher than 3.7V. Theoscillator runs free when Pin 9 is connected to Gnd.
10 CT The normal mode oscillator frequency is programmed by the capacitor CT choice together with the Rrefresistance value. CT, connected between Pin 10 and Gnd, generates the oscillator sawtooth.
11 Soft-Start/Dmax/Voltage-Mode
A capacitor, resistor or a voltage source connected to this pin limits the switching duty-cycle. This pin can beused as a voltage mode control input. By connecting Pin 11 to Ground, the MC44603 can be shut down.
12 RP Standby A voltage level applied to the RP Standby pin determines the output power level at which the oscillator will turninto the reduced frequency mode of operation (i.e. standby mode). An internal hysteresis comparator allows toreturn in the normal mode at a higher output power level.
13 E/A Out The error amplifier output is made available for loop compensation.
14 VoltageFeedback
This is the inverting input of the Error Amplifier. It can be connected to the switching power supply outputthrough an optical (or other) feedback loop.
15 RF Standby The reduced frequency or standby frequency programming is made by the RF Standby resistance choice.
16 Rref Rref sets the internal reference current. The internal reference current ranges from 100µA to 500µA. Thisrequires that 5.0kΩ Rref 25kΩ.

Block diagram of MC44603
Figure 8-13
Operating description of MC44603The input voltage Vcc (pin 1) is monitored by a comparator with hysteresis, enabling the circuit at 14.5V and disabling the circuit below 7.5V. The error amplifier compares a voltage Vfb (pin 14) related to the output voltage of the power supply, with an internal 2.5V reference. The current sense comparator compares the output of the error amplifier with the switch current Isense (pin 7) of the power supply. The output of the current sense comparator resets a latch, which is set every cycle by the oscillator. The output stage is a totem pole, capable of driving a MOSFET directly.
Start up sequence of P816 t1: Charging the capacitors at VccC829 will be charged via R823 and R832, C833 and C811 v ia R829. The output is switched off during t1.t2: Charging of output capacitorsWhen the input voltage of the IC exceeds 14.5V, the circuit is enabled and starts to produce output pulses. The current consumption of the circuit increases to about 17mA, depending on the external loads of the IC. At first, the capacitors at the Vcc pin will discharge because the primary auxiliary voltage, coming from winding 7-9 is below the Vcc voltage. At some moment during t2, the primary auxiliary voltage reaches the same level as Vcc. This primary auxiliary voltage now determines the Vcc voltage.t3: RegulationThe output voltage of the power supply is in regulation.t4: OverloadWhen the output is shorted, the supply voltage of the circuit will decrease and after some time drop below the lower threshold voltage. At that moment, the output will be disabled and the process of charging the Vcc capacitors starts again. If the output is still shorted at the next t2 phase, the complete start-and stop sequence will repeat. The power supply goes in a hiccup mode.

is switched off when the current sense level exceeds the level at the output of the error amplifier.TimeON phase : A drain current will flow from the positive supply at pin 2 of the transformer through the transformer's primary winding, the MOSFET and Rsense to ground. As the positive voltage at pin 2 of the transformer is constant, the current will increase linearly and create a ramp dependent on the mains voltage and the inductance of the primary winding. A certain amount of energy is stored in the transformer in the form of a magnetic field. The polarity of the voltages at the secondary windings is opposite to the primary winding so that the diodes are non-conducting in this phase.TimeDIODE phase : When the MOSFET is switched off, energy is no longer supplied to the transformer. The inductance of the tranformer now tries to maintain the current which has been flowing through it at a constant level. The polarity of the voltage from the transformer therefore reverses. This results in a current flow through the transformer's secondary winding via the now conducting diodes, electrolytic capacitors and the load. This current is also ramp shaped but decreasing.TimeDEAD phase : when the stored energy has been supplied to the load, the current in the secondary windings stops flowing. At this point, the drain voltage of the MOSFET will drop to the voltage of C821 with a ringing caused by the drain-source capacitance with the primary inductance.The oscillator will start a next cycle which consists of the above described three phases. The time of the different phases depends on the mains voltage and the load.TimeDEAD is maximum with an input of 400VDC and a minimum load. It will be zero with an input of 100VDC and an overload.

Circuit description of P816
Input circuitThe input circuit consists of a lightning protection circuit and an EMI filter.The lightning protection comprises R819.The EMI filter is formed by C820, L820, C825 and C826.It prevents inflow of noise into the mains.
Primary rectifier/smoothingThe AC input is rectified by rectifier bridge D802 and smoothed into C821. The voltage over C821 is approximately 300V.It can vary from 100V to 390V.
Start up circuit and Vcc supplyThis circuit is formed by R823, R834, C829, D828, R829,R811, C833 and C811.When the power plug is connected to the mains voltage, the stabilised voltage over D829 (24V ) will charge C833 viaR829. When the voltage reaches 14.5V across C811, the control circuit of Q810 is turned on and the regulation starts. During regulation, Vcc of IC7110 will be supplied by the rectified voltage from winding 7-9 via L832, D832 and C833.
Control circuitThe control circuit exists of Q810, C802, C804, C807, C809,C810, R802, R803, R804, R807, R808, R809 and R810.
C802 and R810 define the frequency of the oscillator.
Power switch circuitThis circuit comprises MOSFET Q825, Rsense R826, R827 andR828, R825, C827, L825, R812 and R813. R825 is a pull-down resistor to remove static charges from the gate of the MOSFET.
Regulation circuitThe regulation circuit comprises opto-coupler Q801 which isolates the error signal from the control IC on the primary side and a reference component D881. The TL431(D881) can be represented by two components: a very stable and accurate reference diodea high gain amplifier
Figure 8-17 ‘TL 431’
TL431 will conduct from cathode to anode when the reference is higher than the internal reference voltage of about 2.5V. If the reference voltage is lower, the cathode current is almost zero.The cathode current flows through the LED of the opto-coupler. The collector current of the opto-coupler flows through R806, producing an error voltage, connected to voltage feedback pin 14 of Q810.
DemagnetisationThe auxiliary winding (7-9) voltage is used to detect magnetic saturation of the transformer core and connected via R801 to pin 8 of Q810. During the demagnetisation phase, the output will be disabled.
Overvoltage protection circuitThis circuit consist of D814, C814, R814, R815 and R816.When the regulation circuit is interrupted due to an error in the control loop, the regulated output voltage will increase (overvoltage). This overvoltage is sensed at the auxiliary winding 7-9.When an overvoltage longer than 2.0 (s is detected, the output is disabled until VCC is removed and then re-applied. The power supply will come in a hiccup mode as long as the error in the control loop is present.
Secondary rectifier/smoothing circuitThere are 5 rectifier/smoothing circuits on the secondary side. Each voltage depends on the number of windings of the transformer.The -8V supply is regulated by voltage regulator Q871.

8.3 CD Main Board
The CD main board is built around the compact disc mechanism VAM1250 and a loader 1250. The CDM delivers diode signals and an unequalised high frequency signal. These signals are necessary inputs for the decoder CD10. Based on these signals the decoder will control the disc. The decoder is able to control the sledge, focus motor, radial motor and turn table. When everything is "locked", the decoder delivers a digital output according to IEC958 standard, subcode to the microprocessor and I2S for reproducing analog audio signals by means of a D/A converter.
The microprocessor controls the CD10 and is slave of the master processor on the CDR main board in the CDR500. Both processors communicate via a DSA connection (data, strobe and acknowledge).

8.3.1 Supply Voltages
DescriptionThe CD main board receives +5V and +12V from the CDR main board via respectively pin 16 and pin 15 of connector 1208. The +5V is split up into +5VHF and +5V. The +5VHF is used mainly for the diode currents and the HF-amplifier. The +5V is used for the digital part of the board. On the board a +3V3 is made from the +5V for the decoder CD10 and an A3V3 for the DAC UDA1320. The +12V is split up into A12V for the audio output stage and +12V for the power drivers of the CDM.
MeasurementsConnect following supplies to next pins :
+5V + 5% to pin 16 of connector 1208. +12V + 5% to pin 15 of connector 1208. Ground reference to pin 17 of connector 1208.
Keep microprocessor 7202 in reset by forcing pin 7 of connector 1208 to +5V. Check the following voltages :
Figure 8-20
8.3.2 Clock Signals
DescriptionThe microprocessor has its own Xtal or resonator of 12MHz.The CD10 needs a clock of 8.4672MHz + 100ppm. This speed also relates to the disc speed. To avoid locking problems between the two drives in the CDR500, both drives run on the same clock. Therefore the CD main board gets the clock for the decoder from the CDR main board via pin 2 of connector 1208.The DAC needs a system clock to drive its internal digital filters and to clock the I2S signals from the decoder. In our case this is 11.2896MHz (CL11) generated by the CD10.
Measurements Connect the power supply as described above in "1.1.1.
Supply Voltages".
Connect on pin 2 of position 1208 a clock signal of 8.4672 MHz ( 100ppm minimum rise time of 50ns and at TTL level (0V and +5V).
Keep microprocessor 7202 in reset by forcing pin 7 at position 1208 to +5V.
Release the reset. Now, the processor will reset the CD10 for at least 75
The output clock CL11 should be available now at pin 42 of the CD10.
Check the following frequencies :

8.3.6 Tray Control
DescriptionThe tray control consists of a TDA7073A power driver (7021) controlled by the processor 7202 via pin 19 TRAYIN and pin 20 TRAYOUT. If pin 20 is low and pin 19 high, the TRAY+ signal at pin 16 of 7021 is forced to +8V and the TRAY- signal at pin 13 of 7021 to GND : the tray will open. If pin 20 is high and pin 19 low, TRAY+ becomes GND and TRAY- becomes +8V : the tray will close. If pin 19 and 20 of the processor have the same value, TRAY+ and TRAY- will have the same value as well : the tray stops moving.
MeasurementsKeep procesor 7202 in reset by forcing pin 7 of connector 1208 to +5V. Connect a load of 15Ω, 7W between pin 3 and 4 of connector 1002. Check the voltage over the load with TRAY+ (pin 3) as positive reference. Check also the levels of pins 19 and 20 of the processor.U TRAY+,TRAY- = <100mVPin 20 = +5VPin 19 = +5VForce pin 20 of the processor to ground, and check the voltages.U TRAY+,TRAY- = -6.5V± 10%Pin 20 = +0VPin 19 = +5VForce pin 19 of the processor to ground as well and check the levels again.U TRAY+,TRAY- = <100mVPin 20 = +0VPin 19 = +0VRelease pin 20 of the processor and check the levels.U TRAY+,TRAY- = 6.5V± 10%Pin 20 = +5VPin 19 = +0VRelease pin 19 of the processor and check the levels again:U TRAY+,TRAY- = <100mVPin 20 = +5VPin 19 = +5V

8.3.7 HF Path
DescriptionThe pre-amplified HF-signal is presented to both n=1 and n=2 amplifier circuits. The mux/demux switches via software and micro processor controlled S1 and S2 lines between either one of the amplified n=1 or n=2 signals. The signal will then follow
another amplification and filtering circuit. The filtering again is controlled by the S1 and S2 lines, dependant on whether the disc starts up (speed n=1, S1 and S2 Low), disc plays at speed n=1 (S1 Low, S2 High) or disc plays at speed n=2 (S1 and S2 High).

8.3.8 Audio Part - DAC
DescriptionThe DAC used, is the UDA1320 bit stream, continuous calibration. I2S signals from various formats can be entered at pins 1,2 and 3. If these signals are in phase with the delivered system clock at pin 6, the DAC will reproduce analog output signals at pins 14 and 16. 0dB level is 0.85Vrms. These analog signals are at 1.65Vdc level.The DAC has features which can be checked on the input pins. Mute will switch off the analog signals. De-emphasis is not used, since this is done in the decoder. Attenuation of -12dB is not used because this is also done in the decoder.
I2SI2S is a kind of digital audio format, consisting out of 3 lines : CLOCK, WORDSELECT and DATA.
WORD-SELECTWord select (WS) indicates whether the data-sample is from the left or the right audio-channel. It has the same frequency as the sample rate of the digital audio signal. This can be 32, 44.1 or 48kHz. Normal polarity is low for a left sample and high for a right sample. So within the low state of the WS-line the data bits for the left channel are transferred, and within the high state the data bits of the right channel are transferred.
CLOCKThe CLOCK signal (CLK) indicates when DataTips must be set, and when DataTips must be read. The frequency depends on the speed of the I2S-bus, but is always a factor of the frequency of the WS-signal. It can be 48x, 64x, 96, 128x... .In our case it is 48x the sample rate frequency = 2.1168MHz. The
signal is in phase with the WS-signal. Transition of the WS always happens on a falling edge of the CLK.
DATADATA contains all data-bits. Data bits are set by the transmitting device, and read by the receiving device. The position of the DATA-bits within the WS-signal is very important. There are several formats for this. In our case we always use Philips I2S format, no Japanese or Sony format. The number of data-bits per channel depends on the used devices. Timing of the I2S-bus, in case of Philips I2S is shown in the next figure :
