FIELD: radio communication.
SUBSTANCE: in device for demodulation of amplitude-manipulated and amplitude-modulated (AM) signals non-linear element is connected between quadripole and high frequency load into transverse circuit, low-pass filter is connected to high-frequency load, quadripole is made of at least two resistive dipoles, values of parameters of which are selected based on condition of provision of required value of depth of amplitude modulation of received amplitude-modulated signal.
EFFECT: higher noise immunity with preset depth of amplitude modulation.
