Abstract

L'invention concerne un circuit de blocage de la tension de retour. Elle est caractérisée par le fait qu'en plus des moyens fonction de la tension d'alimentation servant à doubler la tension, ce circuit comporte des moyens fonction de la tension d'alimentation servant à bloquer un duplicateur de tension à une valeur limite, égale au double d'une tension de seuil déterminée à volonté. L'invention s'applique aux générateurs de balayage électronique.sion codée des 1. Elle a pour objet un procédé de décodage consistant à détecter les transitions de 0 à 1 du signal binaire codé en CMI, à éliminer parmi elles celles apparaissant une période d'élément binaire après les transitions de 1 à 0 qui les précèdent immédiatement et à utiliser les transitions de 0 à 1 restantes pour synchroniser des impulsions de durée égale à une période d'élément binaire et obtenir après complémentation un signal délivrant en NZR-L les données binaires contenues dans le signal codé en CMI. Elle s'utilise avantageusement pour le décodage de signaux numériques de transmission codés en CMI à la jonction d'équipements numériques fonctionnant à un débit binaire très élevé.
