FIELD: physics.
SUBSTANCE: invention is related to the field of signals transmission and may be used as single-band signal generator. Device comprises source of information low-frequency signal, seven multipliers of signals, differentiation unit, integrator, three amplifiers-limiter of signal level, phase inverter, three summators, generator of bearing frequency oscillation, phase changer by 90°, four coherent detectors, divider of single-band signal frequency band in two.
EFFECT: increased width of frequency band and extent of non-working side frequency band suppression.
