Dear antia66,. ?7 V: N6 p3 n7 r
If damping factor is choosen 2, how about the natural freqency?$ f( S! ^( \5 g4 a7 R9 {( T
Will the natural freqency changed with damping factor ?
8 O3 f! |. _4 ^# C- [, u3 HAs 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.
0 [8 ^) q$ E: @6 b0 F q. a7 RHowever, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.9 d! @0 ~* F4 l. @5 G: ?
So, linear model is usually useful. |
