Question

Consider the impedance function Y(s)=(s^2+4s+3)/(3s^2+18s+24). Find the value of C2 after realizing by second Foster method.

(a) 1/16

(b) 1/8

(c) 1/32

(d) 1/64

This question was posed to me in an interview for internship.

I need to ask this question from Synthesis of R-C Network by Foster Method topic in chapter Elements of Realizability and Synthesis of One-Port Networks of Network Theory

Answer 1

Correct choice is (c) 1/32

To elaborate: We obtained R2 as 8Ω and we know C2 = 1/((4)(R2)). So the value of C2 is 1/32 F.

C2 = 1/32 F.
