Nyquist frequency

The Nyquist frequency, also known as the folding frequency or Nyquist limit, is half the sampling rate of a sampled signal, named after engineer Harry Nyquist; frequencies above it alias.

Nyquist plot

A Nyquist plot is a polar plot of a system's frequency response in the complex plane, the basis of the Nyquist stability criterion for feedback systems.

Nyquist rate

The Nyquist rate, also called the Nyquist sampling rate, is the minimum rate for sampling a bandlimited signal, 2B samples per second for bandwidth B, named for Harry Nyquist.

Nyquist stability criterion
