Help with Laplace Transform for PLL VCO, Kvco?????

[Dr. Slick]

Sorry about that -- your original question was a circuits one, and I dropped
into control systems terminology.

The "plant" is the thing you're controlling (the term originally came from
folks learning about controlling steam plants). In this case it's the VCO,
and probably the PD as well (although you can make the claim that the PD
isn't really the plant -- you get to define things the way you want to).
The "controller" is the part you build, so it's the loop filter, in your
case.

That's ok Tim! The PLL is obviously nothing but a control system
anyways.

And i still get some funny looks when i mention "good command following"
of a PLL to another EE.

Thanks for clarifying, the historical part about steam plants is interesting!
