PULSE FREQUENCY-PHASE DISCRIMINATOR Russian patent published in 1994 - IPC

FIELD: radio engineering. SUBSTANCE: pulse frequency-phase discriminator is meant for synthesizer of frequency of automatic control systems. It has D flip-flops 1, 2, 3, 4, 5, 6, NAND gate 7, current generators 8, 9, 10, 11. Discriminator provides for expansion of range of phase discrimination thanks to switching on of additional current generator at moment when modulo 2 difference of phase of input signals is achieved. Current corresponding to this difference of phase is maintained across output of discriminator. EFFECT: expanded range of phase discrimination. 6 dwg
