ABSTRACT:
A method of demodulating an FM carrier wave and an FM demodulation circuit are described which use a phase locked loop. The phase locked loop is tuned to a selected carrier wave frequency including the step of selecting a setting of the variable gain circuit in the phase locked loop to select desired loop gain.
