Dear antia66,
$ A1 @4 _5 } b6 i# ~4 UIf damping factor is choosen 2, how about the natural freqency?
% a: c$ W+ b% E4 `Will the natural freqency changed with damping factor ?0 T0 \6 G* d; o
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.
+ S7 m* h, ?/ ]However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
$ x" W1 J* y. o5 }! F7 F4 L3 aSo, linear model is usually useful. |
