Abstract

a. Montage pour la compensation des erreurs de transmission d'un transducteur auquel peut être raccordée une impédance de charge b. Selon l'invention, est branché en amont du primaire du transducteur W un circuit de sommation R3, R11, R12, R13, V2 à une entrée duquel est appliqué le signal utile, tandis qu'est raccordé au secondaire un dispositif à rotation de phase V3, V4, V5 à déphasage et rapport variables, ce dispositif appliquant aux entrées du circuit de sommation un signal de compensation élaboré pour corriger les erreurs de transmission du transducteur. c. Application notamment à la correction des transformateurs de sortie des amplificateurs de puissance
