Dear antia66,8 f! B+ k( p! n/ \# |! d* F
If damping factor is choosen 2, how about the natural freqency?: q1 b: U- n% h/ |9 i1 q
Will the natural freqency changed with damping factor ?( N7 C9 D1 c8 }9 _2 P
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.
( l' z% c: @$ c6 x8 v( c* C7 xHowever, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
