WebMay 25, 2012 · The Nyquist frequency is always half the sampling frequency, because above that, aliasing occurs: The signal would "fold" back on itself, and appear to be some frequency at or below 500Hz. 2) How do I know the frequencies are between 0 and 500? Shouldn't the FFT tell me, in which limits the frequencies are? WebThe fast Fourier transform (FFT) frequency spectrum of a discrete time signal can be divided into an infinite number of fSAMP/2 frequency bands, also known as Nyquist zones. The frequency spectrum between DC and fSAMP/2 is known as the first Nyquist zone. The frequency spectrum repeats itself over different Nyquist zones.
