In order to recover all Fourier components of a periodic waveform, it is necessary to use a sampling rate at least twice the highest waveform frequency. The
Nyquist frequency, also called the Nyquist limit, is the highest frequency that can
be coded at a given sampling rate in order to be able to fully reconstruct the signal,
i.e.,
at least twice the highest waveform frequency. The
Nyquist frequency, also called the Nyquist limit, is the highest frequency that can
be coded at a given sampling rate in order to be able to fully reconstruct the signal,
