Victor, do you have access to back issues of Radio Communications magazine?
(the excellent RSGB journal).
Look up Rad Comm Sept '84 where on pages 755-758, Steve Price, G4BWE
describes a switched-capacitor filter using the CD4066 quad bilateral
switch. I did not build this project, so cannot offer any recommendation,
although I believe some of the earlier designs suffered from "aliasing"
problems.
