A minimum-phase function has m finite poles and n finite

Home » Control Systems » Control systems miscellaneous » Question

A minimum-phase function has m finite poles and n finite zeros. Its phase angle as ω → ∞ is, where n > m—

1. 0 radians
2. – (m – n) π/2 radians
3. (m – n) π/2 radians
4. π radians

Correct Option: B

Phase angle = – (m – n) π/2 radians where, m = finite poles, n = finite zeros.
