Abstract

RECEPTEUR DE TELEVISION AVEC UN CIRCUIT DEVANT FOURNIR DES IMPULSIONS DE SYNCHRONISATION DE LIGNE ET DE TRAME AUX ETAGES DE SORTIE DE LIGNE 14 ET DE TRAME 30 ET COMPORTANT UN CIRCUIT 5, 6, 7, 9, 10, 20 POUR COMMANDER LA FREQUENCE ETOU LA PHASE D'UN OSCILLATEUR DE LIGNE 11 RELIE A UN CIRCUIT DIVISEUR 21 POUR PRODUIRE DES IMPULSIONS A LA FREQUENCE DE TRAME. CES IMPULSIONS SONT APPLIQUEES, AVEC DES IMPULSIONS DE SYNCHRONISATION RECUES, D'UNE PART A UN ETAGE DE COINCIDENCE DE TRAMES 23 DANS LEQUEL LEURS PHASES SONT COMPAREES, LE NOMBRE DE COINCIDENCES ETANT COMPTE PAR UN COMPTEUR 24, ET D'AUTRE PART A UN COMMUTATEUR COMMANDABLE 29 QUI RECOIT EGALEMENT DES IMPULSIONS DE SYNCHRONISATION DE TRAMES DE LA PART D'UN OSCILLATEUR DE TRAME 27. UN CIRCUIT DE SELECTION 26 COMMANDE UN COMMUTATEUR 29 QUI PASSE D'UNE PART DANS UN MODE DE SYNCHRONISATION INTERNE LORSQUE LA COINCIDENCE PRECITEE A EXISTE DURANT UNE PERIODE DETERMINEE, MODE DANS LEQUEL DES IMPULSIONS DE DIVISEUR COMMANDENT L'ETAGE DE SORTIE DE TRAME 30 ET, D'AUTRE PART DANS UN MODE DE SYNCHRONISATION EXTERNE LORSQUE LADITE COINCIDENCE N'EXISTE PAS, MODE DANS LEQUEL DES IMPULSIONS DE L'OSCILLATEUR DE TRAME 27 COMMANDENT L'ETAGE DE SORTIE DE TRAME. APPLICATION: RECEPTEUR DE TELEVISION.
