I did FFT of a signal in MATLAB. But now I am confused how to normalize it. Whether it should be N or sqrt(N) where N is the length of the signal. Can anyone tell me why & when N or sqrt(N) should be used to normalize?
I have also a basic question. Do we normilize while doing FFT or we normalize it after doing FFT to get PSD?
Thanks in advance
