Question

What is the reflection coefficient If a line is terminated in its characteristic impedance?

(a) 0

(b) Infinity

(c) 2

(d) 0.5

I had been asked this question by my college professor while I was bunking the class.

This intriguing question originated from Standing Waves topic in section Transmission Lines of Avionics

Answer 1

The correct answer is (a) 0

The explanation is: The reflection coefficient of a line that is fully terminated in its characteristic impedance is 0. This is because there is no reflected voltage on the line.
