Aloha Aloha! The Digital Spectrum, calculated by the FFT, is a sampling of the true analog spectrum. If you want to have the frequency samples to coincide with "Fs" sub-multiples, then you can either do what you have done first, that is, use a number of points without zero padding that is implicitly done when say that the number of samples is 2^k, or you can resample your siganl, interpolating the new samples, by using the Rabiner algorithm. OK? Best Regards, Pedro |
