Demodulation of angle-, frequency- or phase- modulated oscillations by detecting phase difference between two signals obtained from input signal; Modifications of demodulators to reject or remove amplitude variations by means of locked-in oscillator circuits the oscillator being part of a phase locked loop with means for eliminating interfering signals, e.g. by multiple phase locked loops
