FIELD: electronic communications; data signal processing. SUBSTANCE: proposed method and device depend for their function on multiplex automatic gain control. Device has signal band-bass filtering unit, target function calculation unit, target function modification unit, multiplying unit, and frequency components integrating unit; newly introduced in device are spectrum amplitude calculator, mean spectrum storage unit, and signal ratio calculator. EFFECT: enhanced suppression of broadband and polyharmonic noise distorting data signals; enhanced contrast of useful signal. 8 cl, 13 dwg
