Question

For the circuit given below, the value of the Transmission parameters B and D are _________________

(a) B = Z, D = 1

(b) B = 1, D = Z

(c) B = Z, D = Z

(d) B = 1, D = 1

This question was addressed to me in an international level competition.

The query is from Advanced Problems Involving Parameters topic in division Two-Port Networks of Network Theory

Answer 1

Correct option is (a) B = Z, D = 1

The best I can explain: V1 = ZI1

And I2 = -I1

B = \(\frac{V_1}{I_2}\)

= \(\frac{-ZI_1}{-I_1}\)  = Z

D = \(\frac{-I_1}{I_2}\)  = 1.
