WebApr 2, 2024 · 1 Answer. An LTI system is said to be minimum-phase if the system and its inverse system are causal and stable. That's implying that all poles and zeros must be strictly inside the unit circle. An all-pass filter 's zero-pole pairs are reflections of each other across the unit circle so that an all-pass filter absorbs the poles or zeros. For a ... WebThe magnitude spectrum represents the gain, and the phase spectrum represents the delay. The all-pass filter was introduced in Chapter 7. An all-pass filter is a causal phase-shift filter. In other words, an all-pass filter is a one-sided filter whose amplitude spectrum is flat and equal to unity. The logarithm of one is zero.
