Phase Locked Loop Block Diagram With Explanation. It performs a comparison of two frequency component fed at its input and generates a dc voltage. Block diagram of a phase locked loop pll the frequency divider downconverts the output by a factor of n and then a phase detector measures the phase difference between the reference signal and the downconverted output.
Phase locked loop pll is one of the vital blocks in linear systems. A phase locked loop or phase lock loop pll is a control system that generates an output signal whose phase is related to the phase of an input signal. It performs a comparison of two frequency component fed at its input and generates a dc voltage.
In this video i have explained phase lock loop by following outlines 1.
The output of the phase detector is the input of the voltage controlled oscillator vco and the output of the vco is connected to one of the inputs of a phase detector which is shown below in the basic block diagram. A basic phase locked loop pll consists of three basic elements. In this video the basics of the phase lock loop pll have been explained by watching this video you will learn the following topics 0 20 applications of p. Need of phase lock loop 4.
