Looks to be an excellent candidate but needs a little bit of work. I've tweaked the lead for accuracy, let me know if you have objections.
This article uses a lot of hardbound references which I am willing to take on good faith unless there's a GAN policy against this. Reviewer: JPatterson (talk) 21:07, 15 February 2010 (UTC)
3rd Paragraph
This paragraph needs some work to make its tone more encyclopedic and less self-referential. It is also unclear in spots.
Distributed element filters make use of a wide variety of different component forms which are described only in broad outline in this article. The one thing they all have in common is that they introduce a discontinuity in the transmission line, which in turns causes a reflection on the line. This manifests itself as a change of impedance at the input to the discontinuity which then appears to have a reactive component, that is, it can be made to appear as an inductor or a capacitor or a combination of these.[2] Lumped element filters are composed of combinations of inductors and capacitors so it is clear that a combination of such distributed elements is, in general, going to have a filtering action.
I'd go with something like
The component forms used to make a distributed element filter all work by creating reactive components that function like lumped inductors and capacitors.[2] This is accomplished by creating discontinuities at points along the transmission line which cause reflections at the discontinuity resulting in a change of impedance which appears as a reactive component to a wavefront traveling down the line. The resulting lumped element equivalent circuit can take the form of any of the classic filter prototypes.
