Question

Consider the impedance function Y(s)=(s^2+4s+3)/(3s^2+18s+24). Find the value of C1 after realizing by second Foster method.

(a) 1/24

(b) 1/12

(c) 1/6

(d) 1/3

The question was posed to me in class test.

Question is 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

Right answer is (a) 1/24

The explanation: The value of C1 is 1/((2)(R1)). As R1 is 12Ω, the value of C1 is 1/24 F.

C1 = 1/24 F.
