WebbAs can be seen, the phase response changes as a function of frequency.Use of extremely-high-order allpass filters can lead to different bands of a signal becoming misaligned in time. This misalignment cannot be reduced or “undone” by addition of more allpass filters.This allpass filter is commonly referred to as a phase rotator.
