Abstract

La présente addition concerne une application aux télécommunications, du circuit de transposition en fréquence objet du brevet principal. Elle décrit l'élaboration des deux tensions en créneaux et de la tension continue, nécessaires au fonctionnement du circuit de commutation faisant partie du circuit de transposition en fréquence à partir de l'onde porteuse correspondante. Elle est applicable à la transposition des groupes primaires à douze voies teléphoniques.
