Question

The driving point impedance of a one-port reactive network is given by Z(s)=5(s^2+4)(s^2+25)/s(s^2+16). After taking the partial fractions, what is the value of H from Z (s)?

(a) 3

(b) 4

(c) 5

(d) 6

I got this question by my college director while I was bunking the class.

Enquiry is from Synthesis of Reactive One-Ports by Foster’s Method in division Elements of Realizability and Synthesis of One-Port Networks of Network Theory

Answer 1

Right answer is (c) 5

Best explanation: By inspection, the value of H is 5.

So H = 5.
