As an example, let us consider a function F(s=25 I and a contour in the s-plane. The mapping of the s- plane unit square contour to the F(s)-plane is accomplished through the relation F(s), and so 20+ l1+jy=F(s)=2+1=2(a+jO)+1 v=20 F(s-plane j2H S-plane 0 2 Bs-plane F(s)-plane As an example, let us consider a function F(s) = 2s + 1 and a contour in the s – plane. The mapping of the s – plane unit square contour to the F(s) – plane is accomplished through the relation F(s) , and so u + j v = F(s) = 2s +1= 2( + j ) +1   2 2 1 =  = + v u
