Non-minimum phase transfer function is defined as the transfer function

The correct option is 1

Concept:

Minimum phase system: It is a system in which poles and zeros will not lie on the right side of the s-plane.

For a minimum phase system:

\(\mathop {\lim }\limits_{\omega \to \infty } \angle G\left( s \right)H\left( s \right) = \left( {P - Z} \right)\left( { - 90^\circ } \right)\)

Where P & Z are finite no. of poles and zeros of G(s)H(s)

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.

In particular, zeros lie on the right side of the s-plane.
