I have the CDs..

Hola, Pedro,

I could scan sections about full lattice filters from Zverev and from
Van Valkenburg into PDFs, if you're interested. For Van Valkenburg,
it's a whole chapter. It would then be left as a "small exercise" to
go from their math to what you want. I suspect a Spice simulation
would be appropriate.

Cheers,
Tom
