Abstract

L'invention concerne un procédé et un dispositif pour injecter et extraire des signaux impulsionnels dans et hors d'un câble alimenté à distance. Selon ce procédé pour injecter et extraire un signal dans une section de câble alimentée à distance par l'intermédiaire de condensateurs à haute tension C1, C2, les distorsions du signal sont atténuées et/ou supprimées au moyen d'une régénération supplémentaire avec conversions successives binaires/pseudo-ternaires/binaires dans des dispositifs comportant des lignes de branchement L1, L2, L3. Application notamment aux systèmes de transmission PCM à large bande.A method and device for injecting and extracting pulse signals into and out of a remotely powered cable is disclosed. According to this method for injecting and extracting a signal in a section of cable supplied remotely via high voltage capacitors C1, C2, the distortions of the signal are attenuated and / or eliminated by means of an additional regeneration with successive conversions binary / pseudo-ternary / binary in devices with branch lines L1, L2, L3. Application in particular to broadband PCM transmission systems.
