Cascade (juggling) and thrown from closer to the middle of the pattern, causing each ball to pass under the ball previously thrown, in a reverse cascade objects are caught near the middle of the pattern and thrown from the outside, causing each ball to pass above the ball previously thrown. Thus from the juggler's perspective the left hand moves in a clockwise motion, and the right hand in a counterclockwise motion. The reverse cascade is generally considered to be more difficult to perform than the cascade, with a difficulty rating of 4 rather than 2 out of 10. The reverse cascade is,
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
