Abstract

GENERATEUR DIGITAL D'IMPULSIONS DE SYNCHRONISATION POUR EMISSIONS DE TELEVISION, FONCTIONNANT DE MANIERE SYNCHRONE. CE GENERATEUR EST BASE SUR LE PRINCIPE D'UN GENERATEUR D'IMPULSIONS D'HORLOGE DONT LA FREQUENCE EST UN MULTIPLE ENTIER DE QUATRE-VINGTS FOIS LA FREQUENCE DE LA LIGNE DE TELEVISION; CE GENERATEUR D'IMPULSIONS D'HORLOGE PRODUIT DES IMPULSIONS DE LARGEUR VARIABLE ET LES DEUX PENTES POSITIVE ET NEGATIVE DE L'IMPULSION SONT UTILISEES POUR OBTENIR L'IMPULSION DE SYNCHRONISATION HORIZONTALE. APPLICATION A TOUS SYSTEMES DE TELEVISION AINSI QU'AUX SYSTEMES NECESSITANT LA MODIFICATION D'UNE IMPULSION ENGENDREE DIGITALEMENT.
