Abstract

Ved en fremgangsmåte til digital-analog-omforming av digitale informasjoner til bipolare analogsignaler benyttes et nettverk av kondensatorer (C-C/16) som er binært avtrappet med hensyn til kapasitet, og som alt etter binær-verdien av denilordnede bit hos et digitalsignal som skal omformes,. med dem av sine belegg som representerer fotpunktet på nettverket, blir koblet til en referansespenningskilde (Vref) eller til jordpotensial og dermed blir eller ikke blir medbestemmende for nettverkets utgangsspenning som representerer analogsignalet. For å skaffe en monoton og såvidt mulig lineær omformerkarakteristikk ved omformingen til bipolare signaler blir nettverket drevet slik at de samme respektive kondensatorer deltar i genereringen av like store positive og negative analogverdier .
