The Nyquist-Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing. (wikipedia.org)
The Nyquist-Shannon sampling theorem is a theorem in the field of signal processing which serves as a fundamental bridge between continuous-time signals and discrete-time signals. (wikipedia.org)
The name Nyquist-Shannon sampling theorem honours Harry Nyquist and Claude Shannon, but the theorem was also previously discovered by E. T. Whittaker (published in 1915), and Shannon cited Whittaker's paper in his work. (wikipedia.org)
The theorem is thus also known by the names Whittaker-Shannon sampling theorem, Whittaker-Shannon, and Whittaker-Nyquist-Shannon, and may also be referred to as the cardinal theorem of interpolation. (wikipedia.org)
