Frequency-locked loop
Webphase-locked loop: A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal. PLLs are used to generate, stabilize, modulate , demodulate, filter or recover a signal from a "noisy" communications channel where data has been interrupted. WebMar 23, 2024 · A Phase-Locked Loop (PLL) is a closed loop whose output signal ϕ is synchronized with the input voltage signal v a b c in phase and frequency. Due to the increasing share of RES, PLLs are increasingly used in the power system.
