Abstract

En slgma-deltateknlkk benyttes til å frembringe en digital representasjon av den innkommende analoge slgnålamplitude. Integreringstrlnnet (72) i omformeren (75) har et analogt feilledd som er knyttet til forholdet mellom et innkommende analogt inngangsslgnal og en referansespenning. Det Innkommende analoge signal blir frakoblet ved avslutning av omfornmlngen. Feilleddet overvåkes med en sammenligner (73) når ladningshoper blir påtrykket Inngangen (70) til integreringstrinnet (72). Antallet av ladningshoper som det er behov for å bringe fellleddet til å krysse null, gir informasjon som kan benyttes til å utvide oppløs- ningsevnen for den analoge til digitale omformer (75).
