FIELD: radio electronics. SUBSTANCE: automatic gain control device has adjustable-gain amplifier incorporating input signal receiving input, control input for receiving gain control signal, and output signal yielding output. AGC device also has measuring circuit for generating received power signal basing on output signal power. Saturable integrator functions to compare received power signal with standard signal and to generate gain control signal in response to result of comparison. Saturable integrator has resolving circuit for resolving integration basing on received power signal, standard signal, and gain control signal. Preferable design version incorporates input limiter in conjunction with analog-to-digital converter. EFFECT: enlarged dynamic range of input signal. 39 cl, 8 dwg
