FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering. Disclosed digital quadrature phase synchronisation and demodulation device is characterised by that it further comprises cascade-connected multiplier device, averaging device, voltage-controlled generator, and a clock pulse generator, outputs of first and second channels quadrature signal processing are connected to first and second inputs of multiplier device, clock pulse generator output is connected to clock input of analogue-to-digital converter, output of first channel quadrature signal processing is output of demodulated phase-shift keyed signal.
EFFECT: providing high-speed digital phase synchronisation and coherent demodulation of signals with binary phase manipulation.
