METHOD OF DEMODULATING PHASE-MODULATED AND FREQUENCY-MODULATED SIGNALS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2014 - IPC H03D3/00 

Abstract RU 2504894 C1

FIELD: radio engineering, communication.

SUBSTANCE: nonlinear element used is a three-pole nonlinear element; the four-terminal element is complex and consists of reactive and resistive elements; the three-pole nonlinear element is connected between the output of the four-terminal element and is connected in a transverse circuit before the low-pass filter by a high-frequency load on a scheme with the common one of three electrodes; the source of the phase-modulated or frequency-modulated signal is connected to the input of the four-terminal element; given relationships between the modulus of the transfer function of the high-frequency part of the demodulator and frequency in order to form a given slope of the amplitude-frequency characteristic are provided by selecting the relationship between the element z11 of a matrix of resistances of the complex four-terminal element and frequency using the following mathematical expression:

EFFECT: high noise-immunity of the receiver.
