Abstract

Oppfinnelsen angår en forbedret digital svitsjeforsterker. Forsterkeren benytter et lavpassfilter (LPF) ved inngangen til svitsje- komparatoren (Ul) for å gi et forbedret signal/ støyforhold i den endelige utgang (V ). I et annet aspekt ved oppfinnelsen, blir en forplantnings- forsinkelse benyttet til å produsere oscillasjon i forsterkerkretsen.
