FIELD: radio engineering. ^ SUBSTANCE: invention is related to the field of radio communication and may be used for demodulation of amplitude-manipulated, and also amplitude-modulated (AM) signals. In method and device for demodulation, AM signal is sent to demodulator (DM) from cascade-connected quadripole (QP), dipole non-linear element (NE), low pass filter (LPF), serially introduced sectional capacitance and low frequency (LF) load. NE is connected into longitudinal circuit between QP and introduced high frequency (HF) load. LPF is connected to HF load, QP is made of number of reactive dipoles, at least two, parametre values of QP are selected from condition of provision of specified AM depth of accepted AM. ^ EFFECT: provision of specified value of AM of received AM signal, which improves noise immunity. ^ 2 cl, 3 dwg |
