Talk:Brick-wall filter

proposed merger with Electronic filter

I considered trying a merge, and having brick-wall filter REDIRECT into a new sub heading under electronic filter#Classification by transfer function but neither seemed as useful as providing a short explanation before linking. My motivation for brick-wall filter was finding the term used in other articles and struggling to understand it. I didnt call it a stub as I didnt think it could usefully be extended. It was more of a REDIRECT (with explanation). Rod57 (talk) 18:40, 25 October 2008 (UTC)
