WebThe Phase-Locked Loop (PLL) is a closed-loop frequency-control system that compares the phase difference between the input signal and the output signal of a voltage-controlled oscillator (VCO). The negative feedback loop of the system forces the PLL to be phase-locked. PLLs are widely used in telecommunications, computers, and other electronic ... WebJul 9, 2015 · A phase-locked loop ensures a telecommunication signal in real time is locked at a certain frequency, if not, it tries to correct the frequency by constant comparing and feedback. PLLs are found in telecommunication channels as stabilizers, modulators, demodulators, noise removers and frequency dividers. WebA phase-locked loop (PLL) can be used to create a complex but high-performance circuit for FM demodulation. A PLL can “lock onto” the frequency of an incoming waveform. It does this by combining a phase detector, a low-pass filter (aka “loop filter”), and a voltage-controlled oscillator (VCO) into a negative-feedback system, as follows: citizen\\u0027s arrest is authorized by:
