Abstract

L'invention concerne un montage pour un système de transmission d'informations à modulation delta. Dans ce système comportant un émetteur S et un récepteur E reliés à des postes T1n et contenant, côté émetteur S, un générateur HG de signaux auxiliaires et, côté récepteur E, un circuit As d'exploitation des signaux incluant un registre à décalage Si et un circuit logique O, un circuit KZ commande un commutateur Se raccordant la source de cadence à un intégrateur à des instants fixés. Application notamment aux systèmes de transmission téléphonique.The invention relates to an assembly for a delta modulation information transmission system. In this system comprising a transmitter S and a receiver E connected to stations T1n and containing, on the transmitter side S, a generator HG of auxiliary signals and, on the receiver side E, a signal processing circuit As including a shift register Si and a logic circuit O, a circuit KZ controls a switch Connecting the cadence source to an integrator at fixed times. Application in particular to telephone transmission systems.
