Question
The driving-point impedance Z(s) of a network has a pole-zero locations as shown in the figure. If Z(0) = 3, then Z (s) is
Options
A.
B.
C.
D.

Correct Answer

Explanation

From figure, The impedance function

The driving-point impedance Z(s) of a network has a pole-zero locations as shown in the figure. If Z

and Z(0) = The driving-point impedance Z(s) of a network has a pole-zero locations as shown in the figure. If Z while in question Z(0) = 3

⟹ The driving-point impedance Z(s) of a network has a pole-zero locations as shown in the figure. If Z = 3 ⟹ k = 2.
