What are the properties of minimum phase transfer function?
1.5 Minimum Phase System
A transfer function G(s) is minimum phase if both G(s) and 1/G(s) are causal and stable. Roughly speaking it means that the system does not have zeros or poles on the right-half plane. Moreover, it does not have delay.
What is the difference between minimum and non minimum phase function?
Minimum phase system: It is a system in which poles and zeros will not lie on the right side of the s-plane. In particular, zeros will not lie on the right side of the s-plane. Non-minimum phase system: It is a system in which some of the poles and zeros may lie on the right side of the s-plane.
What is minimum phase in DSP?
A causal stable LTI system E with transfer function H(z) with all zeros inside the unit circle is called minimum phase. A causal stable system E with transfer function H(z) with all zeros outside the unit circle is called maximum phase.
Why is it called minimum phase system?
In control theory and signal processing, a linear, time-invariant system is said to be minimum-phase if the system and its inverse are causal and stable. The most general causal LTI transfer function can be uniquely factored into a series of an all-pass and a minimum phase system.
