What is a tracking loop?
For that purpose, tracking loops are used in a closed loop to follow continuously the code and carrier parameters of the incoming signal. These loops are often designated as code and carrier tracking loops.
What is the purpose of PLL?
The phase-locked loop (PLL) block is a feedback control system that automatically adjusts the phase of a locally generated signal to match the phase of an input signal. PLLs operate by producing an oscillator frequency to match the frequency of an input signal.
What is PLL and how it works?
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.
Which is an example of PLL?
Automobile race analogy. As an analogy of a PLL, consider a race between two cars. One represents the input frequency, the other the PLL's output voltage-controlled oscillator (VCO) frequency. Each lap corresponds to a complete cycle.
