Abstract : The patent provides a pulse phase demodulator which can extract information from a pulse phase modulated signal whose peak amplitude is near the root means square level of background noise. The pulse phase modulated signal is sampled to determine the maximum signal during a frame cycle to determine its position in the cycle. This position represents the signal intelligence and is converted to a voltage proportional thereto. A feedback circuit means is provided to lock the sampling cycle to the incoming signal.
