Abstract
L'INVENTION CONCERNE UN CIRCUIT DE DEVIATION A COMMANDE DE RETOUR DE SPOT. UN ENROULEMENT 26 DE DEVIATION HORIZONTALE FORME UN CIRCUIT DE RETOUR DE SPOT RESONNANT51 AVEC DEUX CONDENSATEURS DE RETOUR DE SPOT36, 37 CONNECTES EN SERIE PENDANT UN INTERVALLE DE RETOUR DE SPOT. UN CIRCUIT AJUSTABLE54 QUI EST EN PARALLELE AVEC LE DEUXIEME CONDENSATEUR 36 DECOUPLE UNE PROPORTION COMMANDEE DU COURANT DE RETOUR DE SPOT PROVENANT DE CE CONDENSATEUR, DE MANIERE A COMMANDER LA LARGEUR D'IMPULSION DU RETOUR DE SPOT. UNE CORRECTION D'ANALYSE D'IMAGE EST-OUEST, UNE COMMANDE DE LA LARGEUR ET UNE COMMANDE DE L'AMPLITUDE D'IMPULSION SONT EGALEMENT POSSIBLES EN FONCTION DES VARIABLES QUI ONT ETE CHOISIES POUR LA COMMANDE. L'INVENTION S'APPLIQUE NOTAMMENT A DES RECEPTEURS DE TELEVISION.
