Abstract

Un circuit de commande d'ajustement commun est raccordé à plusieurs circuits de contre-réaction sélectivement couplés à un circuit amplificateur pour donner à ce dernier plusieurs gains de base. Le circuit de commande modifie les gains de base en fonction de quantités fractionnelles ou proportionnelles sur des gammes de variation permise de gain établies pour chaque voie, de sorte que les voies sont simultanément calibrées ou corrigées pour des dérives différentes. Application notamment aux amplificateurs de colorimétrie.
