(Phase Lock Loop) an Electronic circuit in digital radios that locks onto your chosen station to give clear drift free reception.
Abbreviation for Phase Lock Loop.
phase lock loop. A circuit for synchronising a variable local oscillator with the phase of a transmitted signal. The circuit acts as a phase detector by comparing the frequency of a known oscillator with an incoming signal and then feeds back the output of the detector to keep the oscillator in phase with the incoming frequency.
A function/device which locks a reference frequency to the phase of an input
State of the art circuitry used in AM/FM tunners designed to capture and hold signal, eliminating station drift.
