The pole-zero map of a rational function G(s) is shown below. When the closed contour Γ is mapped into the G(s)-plane, then the mapping encircles
1
the origin of the G(s)-plane once in the counter-clockwise direction
2
the origin of the G(s)-plane once in the clockwise direction
3
the point -1 + j0 of the G(s)-plane once in the counter-clockwise direction
4
the point -1+ j0 of the G(s)-plane once in the clockwise direction
