Dear antia66,1 b6 Q3 V z p9 v
If damping factor is choosen 2, how about the natural freqency?
5 Y9 C* N7 G' A. B; N$ CWill the natural freqency changed with damping factor ?. k {& r4 U7 D4 w
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.
" v/ y d- b7 b7 s( d; e9 ?( q, mHowever, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
$ q3 K! B& L6 K2 R+ a, s, ~So, linear model is usually useful. |
