Abstract
L'INVENTION CONCERNE UN CIRCUIT DE CORRECTION VARIABLE A SOURCE DE TENSION COMMANDEE. IL COMPORTE ESSENTIELLEMENT DEUX CIRCUITS DE SIGNAUX CONNECTES EN PARALLELE, SOIT ENTRE LA BORNE D'ENTREE 16 ET LA BORNE DE SORTIE 24 DU CIRCUIT, SOIT ENTRE LA BORNE DE SORTIE 21 DU CIRCUIT ET LA BORNE D'ENTREE DE REACTION D'UN AMPLIFICATEUR OPERATIONNEL DONT L'AUTRE ENTREE EST CONNECTEE A LA BORNE D'ENTREE DU CIRCUIT. L'UN DES CIRCUITS DE SIGNAUX CONTIENT UNE PREMIERE IMPEDANCE 18 ET L'AUTRE CIRCUIT DE SIGNAUX CONTIENT UN DISPOSITIF DE REGLAGE D'AMPLITUDE VARIABLE 19 ET UNE SECONDE IMPEDANCE 21. L'INVENTION S'APPLIQUE NOTAMMENT A DES DISPOSITIFS DE TELECOMMUNICATIONS ET A DES DISPOSITIFS D'ENREGISTREMENT SONORE.
