Dear antia66,0 u0 U' r" N" k
If damping factor is choosen 2, how about the natural freqency?. }# ^1 K% I# f! \1 a; @+ V
Will the natural freqency changed with damping factor ?( Q" ?1 u$ e& ~7 N z! X
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.
+ ^. ^: F v/ |However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.7 U$ k2 x& v( p3 l
So, linear model is usually useful. |
