A digital phase detector for processing signals with phase modulation in a wide range of changes in the phase of the received signal is considered. A block diagram of a digital detector with minimal computational costs for the signal period is proposed. The problem of phase jumps when it changes by more than 2π is solved. An estimate is obtained for the noise immunity of a phase detector when exposed to Gaussian noise. Supposed hardware implementation of a phase detector based on field-programmable gate arrays. It can be used in devices for digital processing of the angular modulation signals, devices for controlling the phase of the reference signal and in different measurers.
