Juggling pattern revenge is usually considered the most involved and difficult of the three. A windmill, or false shower, is a juggling pattern which resembles the shower. It is often considered a prerequisite or preparation for Mills Mess, or the other way around. One hand throws outside (or reverse cascade) and the other throws underarm, so that the outside hand catches while crossed over the underarm hand. Siteswap: 3. Siteswap may also be extended to pass juggling. Simultaneous juggling: "<xxx|yyy>" notation means one juggler does 'xxx' while another does 'yyy'. 'p' is used to represent a passing throw. For example the Four-count,
All-pass filter system. For example, by proper choice of pole (and therefore zero), a pole of an unstable system that is in the right-hand plane can be canceled and reflected on the left-hand plane. The benefit to implementing all-pass filters with active components like operational amplifiers is that they do not require inductors, which are bulky and costly in integrated circuit designs. In other applications where inductors are readily available, all-pass filters can be implemented entirely without active components. There are a number of circuit topologies that can be used for this. The following are the most commonly used circuits. The lattice
