A system has transfer function
it is a—1 – s 1 + s
-
- non-minimum phase system
- minimum phase system
- low phase system
- second order system
- non-minimum phase system
Correct Option: A
Non minimum phase system. Since minimum phase system has both poles and zero on the left half of the s-plane. Here the one pole is on left half of s-plane (s = – 1) zero is on right half of s-plane (s = 1). Hence it is non-minimum phase system. Since a non-minimum phase system has at least one pole or zero at the right half of s-plane.
