C) voltage standing wave ration
D) link budget

Question

Quizplus · Accepted Answer

The term given to the difference between the received signal level and the signal level required by the radio to assure there are no errors is known as system operating margin. Option A (free space path loss) refers to the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Option C (voltage standing wave ratio) is a measure of impedance matching in transmission lines. Option D (link budget) is used to calculate and analyze the total gain and loss of a communication system to ensure the signal can be successfully transmitted and received without errors. While link budget includes system operating margin, it also includes other factors such as antenna gain and path loss.
