Abstract

En fremgangsmåte, en anordning og et dataprogram for å forbedre signal/støyforholdet til et signal S(t), der S(t) inneholder nyttesignal og støy, er beskrevet. Det frembringes en måling av S(t) ved en ønsket frekvens. Det frembringes målinger av støy i S(t) ved én eller flere støyfrekvenser der nyttesignaldelen av S(t) forventes å være liten. Støyen ved den ønskede frekvensen estimeres ved hjelp av støymålingene ved den ene eller de flere støyfrekvensene. Den estimerte støyen subtraheres fra målingen av S(t) ved den ønskede frekvensen.
