Dear antia66,
8 a6 O# | Q! N$ _3 l) o& N3 \! @If damping factor is choosen 2, how about the natural freqency?! I; f' ]1 x. t
Will the natural freqency changed with damping factor ?
`7 W. Y: k: B0 b5 \' |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.
- a( I1 o* X2 y L5 e) d" F5 nHowever, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
