Microwave Communication - Engineering

Q1:

In a line with finite attenuation

A power transmission is least efficient when there are no standing waves on the line

B power transmission is most efficient when there are no standing waves on line

C Load power depends on phase constant

D standing waves will always exist on the line

ANS:B - power transmission is most efficient when there are no standing waves on line

If standing waves are not there, whole of the power is absorbed by load.
