Summary:FIELD: radio engineering. SUBSTANCE: device has series-connected first subtracter, first multiplier, first band-pass filter, phase inverter, second multiplier, rejector filter, fourth multiplier, unit with controlled transmission ratio, output of which is connected to second input of first subtracter. Inputs of subtracters are combined to make up device input. First subtracter output serves as device output. Synchronous reference signals are supplied to second inputs of multipliers from output of signal copy generator. Voltage for automatic control of transmission ratio of unit with controlled transmission ratio is formed due to filtering of part of spectrum wide-band interference in band-pass filter, due to its amplification in amplifier and detection in detector of automatic gain control. EFFECT: enhanced interference suppression. 2 dwgn
