How to program a click stimulus?

36 views (last 30 days)
I am ok with matlab but I am not an expert into signal processing:
I would like to know, if someone could give me an example for an acoustic click stimulus?
Since a click contain every Frequency, I dont know how to program such a stimulus.
Thank you in Advance,

The Fourier transform of a square wave pulse is , so use that to synthesise the click —
Fs = 44100; % Sampling Frequency (Hz)
t = linspace(0, 10*Fs, 10*Fs)/Fs; % Time Vector (s)
s = sin(2*pi*(t-5)*5000)./(2*pi*(t-5)*5000); % Click
% sound(10*s(:)*[1 1], Fs) % Listen!
plot(t, s)
xlim([4.995 5.005])
Since x is unbounded (the supoprt is ) it contains essentially all the frequencies (at least up to the Nyquist frequency of the sound card, generally 22050 Hz).
Experiment with the code to get different desired results.
