Hi Dirk,Thank you so much for your reply.I see your point. But the period of a cosine is 2*pi right? Even with this fft length it is not working. What am I still...
Hello everyone,I am trying to remove a phase shift in frequency domain. I simulate a signal  (cosine) and I add time delay in it and I try to reverse it in frequency...

3D fft Matlab

New thread started 5 years ago
Hello everyone. I need some advice regarding 3D #FFT on #Matlab. My signal is represented as a 3D matrix (Let's say 10x10x10) I wanted to find the fft and then...
