Abstract: A method of demodulating an FM carrier wave and an FM demodulation circuit are described which use a phase locked loop. An FM input signal including the carrier wave is supplied to a phase detector in the phase locked loop. The output of the phase detector is filtered and used to generate a signal for use in controlling a voltage controlled oscillator having an output also connected to the phase detector. The phase locked loop is tuned to a selected carrier wave frequency and a variable gain setting of a variable gain circuit in the phase locked loop is selected to select a desired loop gain. The signal for use in controlling the voltage controlled oscillator is varied by the variable gain circuit to alter the amount by which the frequency of the output of the voltage controlled oscillator changes in relation to a given output of the phase detector. The variable gain setting is selected to select a required bandwidth for demodulation.
