Q. If Voltage Standing Wave Ratio, (VSWR) of a wave is 2, its reflection coefficient will be
a. 0
b. 1/3
c. 1/4
d. 1/2
Answer and Explanation:
Answer is 1/3.
The relationship between Voltage Standing Wave Ratio (VSWR) and Reflection Coefficient is given by the Following Equations
SWR=( 1+Γ )/ (1-Γ )—————1
and
Γ= (SWR -1)/( SWR +1) ————-2
From 2 by putting SWR= 2 we will get Γ=1/3
