PHASE-LOCKED LOOP DEVICE WITH FEEDBACK BASED ON INTEGRATED MAXIMUM PRINCIPLE

摘要

FIELD: radio engineering, communication.SUBSTANCE: device includes a reference generator; a tunable generator; an arcsin signal generating unit; a sign signal generating unit; a modulus generating unit; first, second, third, fourth, fifth, sixth and seventh product generating units; first and second sum generating units; an RC filter; an integrating scale converter; a derivative generating unit and a focusing link.EFFECT: shorter capturing time compared to a phase-locked loop device with a single-link RC filter.4 dwg
