Dear antia66,) u5 d6 l$ |0 y! ?% r
If damping factor is choosen 2, how about the natural freqency?
' X, R7 ~' u: A# o- IWill the natural freqency changed with damping factor ?
8 j& U) F. a1 s: f2 ~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., z8 @9 P2 z& i- \" u3 h9 n$ E
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.; ^; S- w( h% K% [0 D
So, linear model is usually useful. |
