Answer 1

Right choice is (d) Attenuation constant Easiest explanation: The peak voltage and current can be directly measured from the standing waves. The standing wave ratio, reflection coefficient and the transmission coefficient can also be calculated from it. Only the attenuation constant cannot be calculated directly.
