METHOD OF AMPLIFYING AND DEMODULATING FREQUENCY-MODULATED SIGNALS AND DEVICE THEREFOR

摘要

FIELD: wireless communications.SUBSTANCE: invention relates to radio communication. Method of amplifying and demodulating frequency-modulated signals is characterised by that four-terminal element is resistive, external feedback circuit used is an arbitrary complex four-terminal element connected in parallel to three polar nonlinear element, three-polar nonlinear element and a feedback circuit as integral unit cascade include between source of frequency-modulated signal with complex resistance and input of resistive four-terminal element, between output of resistive four-terminal element and low-pass filter includes high-frequency load in form of a bi-pole with complex resistance modulus m, and resonant frequency of device is selected to form given quasi-linear slope section of left slope amplitude-frequency characteristics of device in a given frequency band.EFFECT: technical result consists in provision of amplification and frequency demodulation of high-frequency signal due to selection scheme and values of resistances of resistive elements.2 cl, 3 dwg
