#X text 14 20 The all-pass filter has a phase response that depends
on its coefficient \, and a flat frequency response. The coefficient
(p) gives the location of the pole. There is a zero at 1/p \, unless
p=0. If p=0 the filter is effectively a one-sample delay. Negative
values of $p$ are allowed \, as long as p is between -1 and 1;
