FIELD: radio engineering.
SUBSTANCE: information transmission system with frequency separation of signals includes message source (1), modulator (2), master generator (3), five band-pass filters (4, 6, 9, 12, 13), two buffer amplifiers (5, 10), mixer (7), auxiliary generator (8), communication line (11), two amplitude detectors (14, 15) and voltage divider (16).
EFFECT: increasing interference immunity to signal depressions.
