Hi, 
I am writing the mat-lab code for the PLL loop system level, and a stupid question came across my mind, so forgive me if the question seems naive :$
In the closed loop transfer function, I wrote Kvco/S and there is also (S) in the loop filter function. My question is, which frequency should I substitute with in S=jW? I know that W will be the range of frequencies that the PLL produces, but then I thought about the (S) in the loop filter, is it the same? or is it the cutoff of the loop filter? and if it's the cutoff? how can I get it if I already don't know the values of the loop filter parameters?
Thanks in advance,
