FIELD: radio communication.
SUBSTANCE: in device for demodulation of amplitude-manipulated and amplitude-modulated (AM) signals non-linear element is connected between source of amplitude-modulated signals and quadripole into longitudinal circuit, high-frequency load is connected to the output of quadripole, and 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.
