Does anybody know how to generate a signal for this? T=0.01 seconds and sampling frequency = 10000Hz.

[Dimitris Kalogiros]

Are going to use this signal within matlab or simulink ?

clear; clc; close all;

% parameters
T=0.01;
Fs=10E3;
Ts=1/Fs;

% define base signal
s= @(t) ((0<=t) & (t<=T/2))*1

% create wanted signal
t=-T:Ts:5*T;
signal=s(t)+s(t-T)+s(t-2*T)+s(t-3*T);

% plot wanted signal
figure; 
plot(t,signal,'-b.'); zoom on; grid on;
xlabel('t'); ylabel('signal');

Your signal is stored into the "signal" variable.

If you run the script, you will get the following:

Could you explain me please why did you choose 5 in t=-T:Ts:5*T;

And a little explanation for the base signal: s= @(t) ((0<=t) & (t<=T/2))*1

Could you explain me please why did you choose 5 in t=-T:Ts:5*T;

You need 4 replicas of your signal, which is defined inside the interval [0 T]. So I created an interval of duration (1+4+1)*T

And a little explanation for the base signal: s= @(t) ((0<=t) & (t<=T/2))*1

I defined a function, usind the function handler @ , in order to define the "branched" signal (s(t) with the tilde).

Thank you, sir!
