Hello, random signals cannot perform Fourier transform, so it would be better to use PDS for evaluation; The periodic signal can be Fourier transformed, and it will be better to use Autopower spectrum for evaluation. Is this correct? Thank you and look forward to your reply
You guys are amazing, thanks a lot for the innovative way of explaining,love more videos from you
