Abstract

En anordning for gjenkjennelse og bestemmelse av demodulerte data i hvilken et inngangsslgnal (1), såsom et mel- lomfrekvensslgnal eller liknende, demoduleres, og digitale data (9) som svarer til et demodulert basisbåndsignal (3)/ gjenvinnes. Anordningen utmerker seg ved at et sampeltaktsignal (10) med en frekvens på n ganger bithastigheten til de digitale data anvendes for å utføre en samplingsoperasjon ved hvilken en bestemmelse av binærverdien i et antall punkter i basisbåndsignalet utføres for å oppnå en bestenmielse Ifølge en majoritetsregel. Den verdi som bestemmes ifølge majoritetsregelen og deretter anvendes som de demodulerte, digitale data (9), er 1 det vesentlige uten feil som kunne forekomme på grunn av dirring i basisbåndsignalet (3) og andre støykilder.
