Dear antia66,
1 u4 B. v- V2 b, m/ h) yIf damping factor is choosen 2, how about the natural freqency?# v8 E9 K7 _: _1 v
Will the natural freqency changed with damping factor ?* z( U/ ~( w. V; ?" x" L) f: u. i
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.
- P) c3 ~0 C& i& ?- y2 _. [However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
& a: u5 a* V+ K0 a5 w1 W! n# n: WSo, linear model is usually useful. |
