Dear antia66,
- U3 o# M* ]3 I3 m, ^2 R8 f8 n% Z( LIf damping factor is choosen 2, how about the natural freqency?
5 I" s/ C3 {: k& P. |- GWill the natural freqency changed with damping factor ?
. M& ] W/ y, e5 o( GAs 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., N* W' G' G& X
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
/ z1 R( E0 I& i2 eSo, linear model is usually useful. |
