Abstract

DANS UN CIRCUIT MODULATEUR UTILISE EN COMBINAISON AVEC UN DISPOSITIF DE REPRODUCTION MATRICIEL A REGLAGE DE LARGEUR ET D'AMPLITUDE D'IMPULSION, ON PEUT EVITER L'EMPLOI DE REGISTRES DE COLONNE LORSQUE L'INTENSITE DE COURANT POUR UN ELEMENT D'IMAGE SELECTIONNE VARIE DURANT L'IMPULSION SELON LE NOMBRE DE CONTENUS D'UN CIRCUIT DE COMPTAGE UTILISES DURANT L'IMPULSION. LE CIRCUIT MODULATEUR EST ENCORE SIMPLIFIE LORSQUE L'ON UTILISE UNE SOURCE DE COURANT CENTRALE DONT L'INTENSITE DU COURANT VARIE PAS A PAS OU DE FACON CONTINUE AU COURS D'UNE DUREE ENTIERE DE SELECTION DE RANGEE. CE CIRCUIT MODULATEUR PERMET DE FACON SIMPLE L'OBTENTION D'UN NIVEAU D'OBSCURITE REGLABLE, SANS ADDITION D'UNE SOURCE DE COURANT OU D'UN COURANT DE REFERENCE SUPPLEMENTAIRE. APPLICATION: RECEPTEUR DE TELEVISION.
