FIELD: radio engineering.
SUBSTANCE: proposed signal demodulator using sixteen-position amplitude-keying quadrature keyboard (KAM-16) functions to generate code from optimal value in first reversing channel in case of deviation of transfer gains in each channel incorporating, among other things, series-connected phase detector, low-pass filter, and controlled amplifier counter; this code, being proportional to deviation of transfer gains in each channel, closes automatic gain control loop in cophasal and quadrature channels.
EFFECT: enhanced noise immunity due to enhanced precision of transfer gain identity maintenance in demodulator channels.
