Hello,
I'm trying to visualize the fourier transform of a pseudo random sequence with Matlab, and I'm struggling with "sampling" the sequence with enough samples to display a very noticeable sinc response..any suggestions on how to do this?
thanks! Jorge

By pseudo random sequence do you mean a white noise sequence created with something like randn()? If so, why would that have a sinc-shaped response in the Frequency domain?
To illustrate a sinc-shaped response, you can do something like this:
h = 1/10*ones(10,1);
plot(abs(fftshift(fft(h,64))))
