GUI DIGITAL ELECTRONICS SIMULATION LAB

DIGITAL……??? WHAT IS DIGITAL ELECTRONICS? * It is a world of electronics in which we play

with two numbers only. * Digital circuits use transistors to create

logic gates in order to perform Boolean logic. This logic is the foundation of digital electronicsand computer processing. Digital circuits are less susceptible to noise or degradation in quality than analog circuits.

Easier to design. Exact values of voltage or current are not important, only the range (HIGH or LOW) in which they fall.

Information storage is easy.

Accuracy and precision are greater.

Digital circuits are less affected by noise. As long as the noise is not large enough to prevent us from distinguishing a HIGH from a LOW.

More digital circuitry can be fabricated on IC chips.

Advantages of digital electronics:-

1. Convert the real-world analog inputs to digital form (ADC)

2. Process (operate on) the digital information.

3. Convert the digital outputs back to real-world analog form (DAC)

Disadvantage of digital electronics:-

1.Full adder& full subtractor2.Mux & Demux3.Binary to BCD convertor4. flip-flops:- 1.jk flip flop 2.S-R flip flop 3.D-flip flop 4.T-flip flop

We have designed the circuit of…..

5.Counters:- 1.3-bit synchronous up counter 2.3-bit synchronous down counter 3.3-bit synchronous up down counter

4. Asynchronous counter

6.Registers:- TYPES OF REGISTER:- 1.4-BIT SERIAL-IN SERIAL OUT 2.4-BIT SERIAL-IN PARALLEL OUT 3.4-BIT PARALLEL IN PARALLEL OUT 4. 4-BIT PARALLEL IN SERIAL OUT 5. UNIVERSAL REGISTER

FULL ADDER AND FULL SUBTRACTOR:

full adder is a circuit which add 3-BIT.

Full subtractor is a circuit which gives the difference between 3 BIT.

EXPLANATION:

What is mux??.....

MUX acts as a data selector in which several input and one output.

Multiplexer means many into one. A multiplexer is a circuit used to select and route any one of the several input signals to a signal output

Demux

Demultiplexer means one to many. A demultiplexer is a circuit with one input and many output.

Demux acts as a data distributor.

Flip flop circuit:- It’s a circuit which can store 1-bit data. It is

used in RAM,ROM…….etc

Counter circuit:- Counter circuit is used to count pulses. And

also used for delay purpose.

J-k flip flop:-

S-R flip flop:-

D-flip flop:-

T-flip flop:-

3-bit synchronous down counter:-

3-bit synchronous up counter:-

3-bit synchronous up down counter:-

1-bit magnitude comparator:-

Multiplexer:-

Graphical User Interface.

It  is a type of interface that allows users to interact with electronic devices through graphical icons.

It is a user friendly window. User can easily perform experiments NOW.

We have introduced GUI and voice with matlab…….
