It turns out I am under moderation, and I don't know how to get out of it.

So this is my second post, hopefully a few more and I will be free.

I do apologize, I typically would add helpful and enlightening posts to someones thread, but I don't know enough to really be useful.

Oh, as far as C3 is concerned-- I was curious.

From what I have seen, a good reason to include C3 is because it basically doubles its effect in the filter. What other reasons are there to include it?

(By doubling, I mean connected as such, there is a virtual ground in the middle of it, and so the capacitor can be modeled as 2*C3 on both sides, going to ground, just like the first schematic. This is all basic to most of you, but its something I at least know )
