Dear antia66,' x4 q( Y# H# _8 Z
If damping factor is choosen 2, how about the natural freqency?: Q! t1 Y+ ]5 V8 \
Will the natural freqency changed with damping factor ?- n/ `+ m0 g3 r6 j+ ~
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+ Y( G3 o( G* H5 }% t+ I
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
+ i& C" j0 y+ y! x6 V+ `So, linear model is usually useful. |
