An all-pass filter is a signal processing filter that passes all frequencies equally in
gain, but changes the phase relationship among various frequencies. It does ...
signal intact, but introduces phase shift is called an allpass filter. The purpose of
this ... Figure 3 and Figure 4 summarize design equations for various active filter
The allpass filter is an important building block for digital audio signal processing
systems. It is called ``allpass'' because all frequencies are ``passed'' in the ...

filter is that which passes all frequency components of the input signal ... The all-
pass filters are also called delay equalizers or phase correctors.
There is a fairly large literature thread on the topic of allpass filter design.
Generally, they fall into two main categories: parametric and nonparametric
