Abstract

L'invention concerne les convertisseurs analogique-numé rique. Le convertisseur de l'invention comporte un étage de conversion grossier 3 et un étage de conversion fin 7. Le signal de sortie de l'étage 3 est reconverti sous forme analogique pour être soustrait du signal analogique d'entrée, avant d'être applique à l'étage 7. Un circuit de commutation 2 remplace périodiquement le signal d'entrée par une tension de référence VA pour permettre la correction des dérives en courant continu Application au traitement des signaux vidéo.
