FREQUENCY-PHASE DISCRIMINATOR Russian patent published in 2019 - IPC H03D13/00 

FIELD: computer equipment.

SUBSTANCE: invention relates to automatics and computer engineering. Frequency-phase discriminator comprises second phase comparison unit, first and second outputs of which are connected to first and second inputs of decoder, first input is combined with first input of first phase comparison unit and is first input of frequency-phase discriminator, and second input is combined with second input of first digital switch, with clock inputs of third trigger and pulse counter and connected to output of second frequency divider, information input of which is connected to second output of computing device, and input is combined with input of first frequency divider and connected to output of high frequency generator, output of first frequency divider is connected to second input of first phase comparison unit and to clock inputs of first and second triggers, information input of the first frequency divider is combined with the second information input of the computing device and is the second input of the frequency-phase discriminator. Invention relates to automatics and computer engineering and can be used in phase synchronization systems and systems of precision synchronous-in-phase electric drive.

EFFECT: technical result is wider measurement range frequency mismatch.
