Matched Filter

Det matchede filter er en optimal signaldetektor, der maksimerer signal-støj-forholdet (SNR) til detektion af et kendt signal i additiv Gaussisk støj. Udviklet af D. O. North under Anden Verdenskrig til radaranvendelser, repræsenterer det matchede filter det optimale lineære filter til signaldetektion og udgør fortsat grundlaget for detektionsteori og digital kommunikation.
