How does PSD accuracy change with FFT size?
The sampling frequency should be twice or more than twice the highest frequency in the signal. If you do not follow this rule, you will get aliasing, no matter what your FFT length is. … The frequency resolution (Hz) = 1/Time_length (s) of the signal that you input. Yes this relationship can also be written in terms of the FFT length and the sampling frequency. …
