FIELD: devices for automatic acoustical-frequency signal correction.
SUBSTANCE: proposed processor incorporating provision for automatic frequency correction throughout entire spectrum of output signal in compliance with arbitrarily specified requirements, that has band filters, groups of variable-gain amplifiers, analog adder, and control unit depends for its operation on comparison of source signal spectrum with reference values dictating desired waveform of spectrum at output, on formation of control actions, and on transmission of these actions to controlled amplifiers without forming feedback circuits.
EFFECT: enlarged input signal spectrum width for frequency correction in compliance with arbitrarily specified requirements.
