Abstract

PROCEDE DE TRANSMISSION DE SIGNAUX DE COMMANDE DE DENSITE DE LIGNE DE BALAYAGE AUXILIAIRE, DANS UN SYSTEME DE TELEGRAPHIE DE FAC-SIMILE. UN SIGNAL DE COMMANDE DE DENSITE DE LIGNE SUR LE COTE RECEPTEUR EST TRANSMIS PENDANT UNE PERIODE D'EMISSION D'UN SIGNAL DE PHASE, ENTRE UN SIGNAL D'IMAGE D'UNE LIGNE ET UN SIGNAL D'IMAGE D'UNE LIGNE SUIVANTE. L'INVENTION S'APPLIQUE PARTICULIEREMENT A LA TRANSMISSION DE TEXTES.
