2. the sum of the filter outputs equals the
original input.
This is a *hard* problem. Basically none of the classical filter
types have these properties. There are filter sets that can do
this but they are quite esoteric.

I'm pretty sure they can just be converted to the digital domain
using the bilinear transform.
