I want to design a single cycle square wave and for theat I am using 'square' function but I don't know how to make it a single cycle wave.
I'm not exactly sure that for this purpuse I need to change the duty cycle or not, however I feel that's the case. But I wanted to ask professionals here to assure that.
This is my code for that:
f0=2.25e6;
fs=100e6;
t2=0:1/fs:2/f0;
offset=0;
amp=1;
duty=50;
sq_wav=offset+amp*square(2*pi*f0.*t2,duty);
plot(t2,sq_wav)

% For single square pulse, you can specify:
% pulse width: pw
% simulation time: T
f0=2.25e6;
pw = 1/f0/2;
fs=100e6;
T=2/f0;
offset=0;
amp=1;
%duty=50;
ns = round(T*fs);
t2 = (0:ns-1)/fs;
sq_wav = zeros(ns, 1);
sq_wav(1:ceil(pw*fs)) = 1;
sq_wav=offset+amp*sq_wav;
plot(t2,sq_wav)

Number of samples (ns) in the square wave is the prodcut of the simulation time (T) and the sampling frequency (fs) (which is number of samples per unit time).
