Abstract

L'INVENTION CONCERNE UN CIRCUIT DE CONVERSION D'UN SIGNAL ASYMETRIQUE EN UNE PAIRE DE SIGNAUX SYMETRIQUES. CE CIRCUIT COMPORTE UN PREMIER CIRCUIT DE DEUX DIODES EN SERIE CONNECTE EN PARALLELE AVEC UN SECOND CIRCUIT D'UNE DIODE EN SERIE AVEC LE CIRCUIT COLLECTEUR-EMETTEUR D'UN TRANSISTOR, DONT LA BASE EST CONNECTEE AU POINT COMMUN ENTRE LES DIODES DU PREMIER CIRCUIT. LE SIGNAL D'ENTREE EST APPLIQUE ENTRE CES DIODES ET LES SIGNAUX DE SORTIE SONT PRELEVES AU POINT COMMUN ENTRE LES DIODES ET AU COLLECTEUR DU TRANSISTOR. L'INVENTION S'APPLIQUE NOTAMMENT A LA COMMANDE AUTOMATIQUE DE CHROMINANCE D'UN RECEPTEUR DE TELEVISION EN COULEURS.
