Mills' Mess caught and is holding a ball), the Mills Mess pattern is sometimes called "Inside Out" -- from its appearance when performed: alternate chops alternating from "inside the pattern" to "outside the pattern", making it seem almost as if the balls are juggling the hands. The effect is that of a juggler frantically pursuing the balls in their staccato movements. The American artist, Glenn (with no last name) aka "The Great Bongo", gave this pattern its name, and claims to have taught hundreds of jugglers "how to do it the easy way." Mills Mess is a shape distortion involving crossing and
Constant k filter that. The design techniques used by Campbell have largely been superseded. However, the ladder topology used by Campbell with the constant k is still in use today with implementations of modern filter designs such as the Tchebyscheff filter. Campbell gave constant k designs for low-pass, high-pass and band-pass filters. Band-stop and multiple band filters are also possible. Some of the impedance terms and section terms used in this article are pictured in the diagram below. Image theory defines quantities in terms of an infinite cascade of two-port sections, and in the case of the filters being discussed, an infinite ladder
