Re: Matlab Help

Why dont you use the Matlab help?

It pretty simple I think. Generate the chirp signal then take its FFT and then plot it

t = 0:0.001:2; % 2 secs @ 1kHz sample rate
y = chirp(t,0,1,150);
f=fft;
plot(f)

Maybe i dont understand the concept of Chirp very well!.
Any good material on Chirp modulation and the equations?
