The highest frequency that can be represented in a digital signal of a specified sampling frequency. It is equal to one-half of the sampling rate.
See Nyquist Theorem.
- Nyquist theorem
communications A theorem stating that when an analogue waveform is digitised, only the frequencies in the waveform below half the sampling frequency will be recorded. In order to reconstruct (interpolate) a signal from a sequence of samples, sufficient samples must be recorded to capture the peaks and troughs of the original waveform. If a waveform […]
