I am new to PLL and would like to find out some answers below:
1. What is a full rate & half rate phase detector? which is better? is digital PFD a full rate detector?
2. Why do we use lag-lead loop filter in PLL? why not just lag filter (normal LPF)? is it for stability purposes?
3. Which type of loop filter is most commonly used? active lag filter or active PI filter & why?
