fast fourier transform

Started by shiva_r97 January 15, 2007
Hi all,

I am new to signal processing as well as matlab.

I have a symmetrical rectangular pulse in time domain.
I would like to peform fourier transform of this signal using fft
command using matlab.

I would like to obtain the same results using continuous fourier
transform (for this case I have a analytical solution which is a
function of frequency 'f').

I would like to plot the results from matlab and this analytical
method (magnitude and phase vs frequency) for the comparison.

I need help regarding this.

Thanks in advance

Regards
Shiva
