Draw and explain PLL as an FM demodulator.

Description : Draw and explain PLL as an FM demodulator.

Last Answer : Explanation:- FM signal which is to be demodulated is applied to input of PLL.VCO output must be identical to input signal if PLL is to remain locked. As PLL is locked, VCO ... error voltage represents the modulating signal. Thus at the error amplifier output we get demodulated FM output.
