Title: FM signals demodulator system - has automatic compensation device to reduce out-of-tolerance or temp. shift errors
Inventor: ZECH RONALD DIPL ING
IPC: H03D3/18
Filed: 1976-12-23
Abstract: An FM demodulator system has one or more frequency-dependent networks, built up of capacities and inductances. It develops an output signal at the modulation frequency, with provision for compensation of errors due to manufacturing tolerances or temperature effects on the electrical characteristics, without special measures of adjustments. The result is obtained by arranging that the position of the range of operation of the frequency-dependent network is controlled by a regulating voltage derived from the output voltage at modulation frequency. The regulating voltage is preferably the time-averaged mean of a pulsating DC voltage derived from the AC output voltage.
