FIELD: radio engineering, communications.
SUBSTANCE: input signal is sent to a demodulator, made of a quadripole, a non-linear element, an integrating low pass chain-filter, a separating tank and a low-frequency load, additional amplitude modulation of input signals is carried out by means of supply of these signals to the left slope of the amplitude-frequency characteristic of the demodulator, with the help of a non-linear element the spectrum of received signals is broken into high-frequency and low-frequency components, the low-frequency component is sent to the integrating low pass chain-filter, with the help of which an information low-frequency signal is separated. At the same time the quadripole is made as complex from reactive and resistive elements, and dependences of elements in the matrix of resistances of the complex quadripole on frequency are defined with the help of the specified mathematical expressions.
EFFECT: expansion of areas of physical performability.
