Phase-Domain PLL Analysis Using MATLAB

 Learn about the concept of phase-domain PLL modeling using MATLAB® as a demonstration tool. Watch an explanation of what a phase-domain model is and how it is contrasted against a time-domain PLL. Next, the pros and cons of phase-domain models will be discussed; it’s primarily a speed versus fidelity versus usability tradeoff. Finally, see an example of phase-domain modeling of a charge pump PLL in MATLAB. 

The MATLAB-based example has two parts: The first part leverages Control System Toolbox™ to derive the frequency and step responses while the second example only uses base MATLAB functions to do the same thing. This is an all-MATLAB approach to PLL modeling. Future videos will show how Simulink® is used for simulating PLL behavior.
