anita66 兄,是否能跟刘教授联系下,把他的PPT贡献上来呢^_^

Dear antia66,
- C' l- O( G* Q% o) RIf damping factor is choosen 2, how about the natural freqency?
6 n: e: `6 H. ~; e3 `Will the natural freqency changed with damping factor ?
As my understanding, choose bandwidth <= 1/10*reference freq is for linear model is valid or not, that is, if need widther bandwidth PLL, the parameter from continuous model cannot provide expected PLL behavior.
3 V1 D* S# k7 {7 oHowever, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
% p  A/ N4 T( }0 {So, linear model is usually useful.
