Abstract
A circuit for minimizing non-linearity of an FM-demodulator which is in the form of a phase control circuit whereby its voltage controlled oscillator is controlled by adjusting the voltage applied to a capacitive diode coupled thereto so as to adjust the zero-axis crossing of the demodulator to coincide with the center frequency of the input signal to be demodulated.
