    Do you have a schematic of a Sallen Key filter that you need to analyze?

    Post the schematic and I will give it a try.

    What do you mean by solve?

    You can solve for the transfer function of nearly any opamp-based circuit as long as you can handle a bit of math. You can treat the opamp as ideal if you want to save paper :p
