Mills' Mess variant of the Boston Mess in which every catch from one hand is clawed. Eric's Extension, invented by Eric Uhrhane, is a variation on Mills Mess in which the arms cross twice on each side instead of just once. The extra throws may add to the visual appeal of the pattern. Eric's Extension requires the juggler's arms to be slender or flexible to cross two times, a requirement which makes this variation physically impossible for some. It is especially difficult with clubs. When combined with chops (a "chop" is a downward sweep or flourish of the hand that has just
All-pass filter results in transformer action between the two inductors and an all-pass response even at high frequency. The bridged T topology is used for delay equalisation, particularly the differential delay between two landlines being used for stereophonic sound broadcasts. This application requires that the filter has a linear phase response with frequency (i.e., constant group delay) over a wide bandwidth and is the reason for choosing this topology. A Z-transform implementation of an all-pass filter with a complex pole at formula_9 is which has a zero at formula_11, where formula_12 denotes the complex conjugate. The pole and zero sit at the
