Dear antia66, l7 J4 T/ p9 [6 m% p f: r0 L
If damping factor is choosen 2, how about the natural freqency?. o8 k+ P' J: K& ^
Will the natural freqency changed with damping factor ?+ ]+ A, w0 b. J$ |' R
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.) M4 |: J8 `+ d- h; d( A: D
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
