Subject:  problem on inverse fourier transform from sinc pulse to rectangular pulse, need help 
Date:  Sat, 4 Mar 2000 15:03:26 0800 
I want to model stair wave y=2 as 0<x<1 y=1 as 1<x<2 y=0 as 2<x<3 through it fourior transform from sinc pulse We know As So
so fourier transform of stair wave y=2 as 0<x<1 y=1 as 1<x<2 y=0 as 2<x<3 as
so I inverse fourier transform U(f) that would my assumed stair wave pulse. I attach my mat and fig file from matlab student version5.3 for window. But it didnot do what I want.
x=0:0.01:3; EDU»
y=ifft((sinc(x)*(2*exp(i*pi*x)+exp(i*3*pi*x)))); EDU»
y=ifft((sinc(x).*(2*exp(i*pi*x)+exp(i*3*pi*x)))); Where I may go wrong?
Need your tech help and thanks in advance Eric(address@hidden)
