}}</ref> is a technique for converting a [[continuous-time]] filter design to a [[discrete-time]] filter ([[digital filter]]) design.

The method works by mapping all poles and zeros of the [[Laplace transform|''s''-plane]] design to [[Z-transform|''z''-plane]] locations ''<math>z=e<sup>^{sT}</supmath>'', for a sample interval ''<math>T''=1 / f_\mathrm{s}</math>.<ref>
