Question

The reflection co-efficient of a transmission line having characteristic and load impedances as 30$\Omega$ and 50$\Omega$ respectively is

• A. $\frac{3}{4}$
• B. $\frac{1}{8}$
• C. $\frac{1}{4}$
• D. $\frac{1}{2}$

Answer 1

The correct option is C $\frac{1}{4}$

Reflection coefficient, $\Gamma =\frac{Z_L-Z_0}{Z_L+Z_0}=\frac{50-30}{50+30}=\frac{1}{4}$
