Re: Any formula about settling time and loop-filter bandwidt
Najfi, this link cannot work!
khouly,
damping factor is .2 ? I think the PLL with this value does not have good performance.
The recommended value is 0.707.
eda4you,
What's the meaning of Tau?Pls explain it!
settling time formula
As we can see, the wider the loop-filter's bandwidth,the shorter the settling time.
Now I want to know the exact formula revealing this relative!
Thank you!
Re: Any formula about settling time and loop-filter bandwidt
eda4you: Thank you for your reply!
I'm puzzled by this formula.
If comparision frequency is 25MHz,and suppose the loop bandwidth is 500KHz,according to the equation BW*Tau = 1,
Tau should be 1/500,000=2uS.
But in PLL circuit, it is...
As we can see, the wider the bandwidth,the shorter the settling time.
Now I want to know the exact formula revealing this relative!
Pls help me,thank you!
Hi guys,
Pls tell me some theory and tricks on designing waveguide filter with capability of supressing harmonic.For example,8-10GHz BPF,with 40dBc attenuation among 16-20G.
I cannot carry on with my work now.
Response is appreciated!
I want to know the difference at performance and phyical size between combline resonators with ground plane between resonator posts and reactangular cavity resonators without resonator posts in the cavity.
Thanks!
need cavity filter paper

I want to design a powermeter for measuring pulse signal.
But I have no references on it.
Please give me the diagram of powermeter or recommend some papers to me.
And please explain the difference between pulse powermeter and constantwave powermeter.
If constant wave signal is measured by...
