Abstract

Convertisseur numérique-analogique destiné à convertir un signal numérique en facteur de mise sous tension d'un signal constitué par un train d'impulsions et à établir la moyenne du signal d'impulsions à l'aide d'un filtre passe-bas pour le convertir en un signal analogique. Ce convertisseur comprend un générateur d'impulsions de base 5, un générateur d'impulsions de base auxiliaire 6, un circuit porte 7, un générateur de signal pulsatoire de sortie 8, et un filtre passe-bas 9.
