Question

Consider a function Z(s)=5(s+1)(s+4)/(s+3)(s+5). Find the value of R2 after performing the first form of Foster method.

(a) 1

(b) 2

(c) 3

(d) 4

I have been asked this question by my college director while I was bunking the class.

Origin of the question is Synthesis of R-L Network by the Foster Method in chapter Elements of Realizability and Synthesis of One-Port Networks of Network Theory

Answer 1

The correct option is (b) 2

The explanation is: We obtain P2 as 2.

R2=P2.

So the value of R2 is 2Ω.

R2 = 2Ω.
