Ф(σω) = Tзад.ф•σw,
где Tзад.ф - наклон характеристики, определяющий задержку, σω - изменение частоты относительно wo равной частоте несущего колебания демодулируемого сигнала.The proposed method and device of relative phase demodulation relate to radio engineering and communications, in particular to devices for receiving and demodulating signals with phase and relative phase modulation, and provide a simpler and more accurate setting of the equipment. The method of relative phase demodulation using phase detection relative to the reference signal is characterized in that the reference signal is obtained by exerting a time delay on the modulating phase change of the demodulated signal. A relative phase demodulation device containing a phase detector, one of the inputs and the output of which are the input and output of the device, is characterized in that a delay circuit with a phase-frequency characteristic in the passband of the demodulated signal is connected between the input of the device and the other detector input
F (σω) = T zad.f • σw,
where T zad.f is the slope of the characteristic that determines the delay, σω is the change in frequency relative to w o equal to the frequency of the carrier wave of the demodulated signal.
