Labview steps:
1- Add two numbers, multiply, subtract
2- Change to indicator
3- Compare data and visualize on led
x < y?
200.00
x+y
y 2
x
4- Generate random numbers between 0 and 1.5- For loop,
oscilloscope, difference between chart scope and graph scopeGraph
for data : vector by vector. chart for point by point.
100
Waveform Graph
number: 0 to 1
100
Waveform Chart
6- Characteristics of a chart scopeTo change the characteristics
of the chart: right click on the scope, advanced,update mode
7-
XY graph (2 for loops+cluster+bundle)
8- While loop, stop the loop after a fixed number of iterations.
Stop after a stop buttonStop is found in Boolean menu
9- Two signals on the same graph

Use array: build array
10-Calculate S=1+2+3+N, P=1*2*3*4*N.Right click on the for or
while then add shift register to create a sn-1from sn.
11-Take the data from while loop to scope, process raw of data:
mean, variance, add, division....Processing of data: Block of mean,
variance, histogram (analyze, mathematics.)See : Analyse
mathematics
12-Process a matrix of data: add values, mean, value at index,
add a value on index to matrixSee : arrayz
13-Save data to disk, txt file (append file or create new
one)See file I/O, then save to disk
14-Case (boolean, numeric, text...)See structures:
Dialog box, Prompt the user, flat sequence.
15-Popup menu, list menu
16-Dialog for data entry, (Dialog, prompt user), Login by String
comparison17-Generate a signal from a signal generator, plot the
signal, Fourier transform, and see the
harmonics.
18-Generate a desired signal using a formula. Choose a formula.
Change the name of the signalin the graph

19-Component of a signal, probe, show Fourier transform with and
without Components, mean
and variance of signal (analyze - signal processing)
20-Generate random signal (white Gaussian noise)
Add white noise to signals, Do Fourier Transform, and PSD.
21-Save signals to disk with parameters.22-Design in Labview.
Multi page design23-Start and stop in the same program

24-Create a sub-vi. Make a program with if then make the
sub-vi25-Choose to plot one signal between two
26-Signal acquisition from national instrument card, Processing
data27-Save signals (waveform, save).28-Filtering of signals. Add a
sine wave a noise then use band pass filter. Add 2 sines then
extract one sine wave
See how to merge signals in one wire. See express, signal
manupilation.

29-Choose a signal, calculate its parameters : statistics
parameters (Skewness, mode, median,average, .) and its histogram.
See express, statistics
30-Comparison between a signal and constant, output is a signal.
See express, arithmetic,comparison
31-Play a waveform
32-Make the Fourier transform of a signal. Make the calculation
on results: Surface on energyband. Division of ratio between two
frequency bands (HRV interpretation). Create a sub
signal from signal (waveform). Add all components then make the
interpretation.
33-Choose file from prompt and dialog. See express input
34-Formula, (Express). Polynomial of second degree
resolution.35-Property node: on program, right click + insert
property node +visible (then position)36-Rapport (express, output,
report)37-Acquire speech signal and then process it
