Solution Problem 6.1:
One pair of zeros of the system is located on the intersections of the vertical through 1/2
and the circle with radius 1 and center 1. Thus, |s 1| = 1 or, ( 1)2 + 2

Solution Problem 7.1:
Let s = x + jy. Then H(s) =
(x1)+jy
.
(x+1)+jy
|H(s)| = a > 0 is given analytically by
(x1)2 +y 2
Hence |H(x + jy)| =
, and the level line
