paul perry	Re: High Q, ultra narrow band parametric filter When making very high Q analog filters, the problem is getting the components accurate, as this becomes more of a problem with high Q. perhaps something could be done with the BurrBrown UAF series, which have precision capacitors inside them already, and are arranged so that various filter configurations can be made by adding precise resistors. I havn't done this myself.
