Dear antia66,
2 T) X! x$ ], LIf damping factor is choosen 2, how about the natural freqency?
& }* z8 |6 s% x) T) mWill the natural freqency changed with damping factor ?7 a$ C) m# ]" N1 S) ~6 D. 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.& o: Z1 j% T8 i0 A" b4 G
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.1 U0 J1 C3 I4 P6 V. A
So, linear model is usually useful. |
