I am currently evaluating the power spectra of a number of process signals. How do I identify the Nyquist frequencies of the various components?

MohamadThe Nyquist frequency is one half (0.5) of the data set sampling frequency.

Let's walk through the rationale:

Therefore, the frequency of the $\frac{N}{2}$ (or $\frac{N}{2}+1$) DFT component is equal to the Nyquist frequency, which is: $\frac{N}{2}* \frac{F_s}{N} = \frac{F_s}{2}$
