Question

Obtain the transfer function Z21(s) in the circuit shown below.

(a) 1

(b) 2

(c) 3

(d) 4

I have been asked this question in my homework.

Asked question is from Network Function for the One-Port and Two-Port topic in section S-Domain Analysis of Network Theory

Answer 1

Correct answer is (b) 2

To elaborate: The transfer function Z21(s) is Z21 (S) = V2(S)/I1(S). V2 (S) = 2 I1(S) => V2 (S)/I1 = 2. On substituting Z21(s) = 2.
