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. 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".
