FIELD: organization of digital data exchange between measurement modules, central information acquisition unit and operator of field telemetering seismic recording equipment. SUBSTANCE: digital communication channel incorporates source of analog signal, source of coder, encoder of communication channel in which noise-immune coding takes place, pulse transformer of transmitter, communication line proper which can be double-wire or radio channel, pulse transformer of receiver, decoder of communication channel in which noise-immune code is decoded, for instance, to standard PCM code, decoder of source, receiver of analog signal, adaptive former of consistent binary signals placed between pulse transformer of receiver and decoder of communication channel. EFFECT: improved noise immunity of digital channel thanks to insertion of adaptive former of consistent binary signals which operation is based on use of criterion of sluggishness of change of amplitude of following information pulse with regard to previous information pulse. 3 dwg
