Dear antia66,
9 _ B9 l7 Y0 w5 U% @1 V! t) nIf damping factor is choosen 2, how about the natural freqency?
. I# |$ z- @% nWill the natural freqency changed with damping factor ?, D$ S9 h' g6 W( s4 C# ^6 s% s
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.# G8 c; ?$ R z6 T% f& ^
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.# Y; o$ e. k( S3 v
So, linear model is usually useful. |
