[[File:Pulse examples.svg|thumb|Examples of pulse shapes: (a) [[rectangular function|rectangular pulse]], (b) cosine squared (raised cosine) pulse, (c) [[Dirac delta function|Dirac pulse]], (d) [[sinc function|sinc pulse]], (e) [[Gaussian function|Gaussian pulse]]]]

A '''pulse''' in [[signal processing]] is a rapid, transient change in the amplitude of a [[signal]] from a baseline value to a higher or lower value, followed by a rapid return to the baseline value.<ref>Ángela Molina, Joaquín González, ''Pulse Voltammetry in Physical Electrochemistry and Electroanalysis'', Springer, 2015 {{ISBN|3319212516}}.</ref>
