gain


gain
i. The amplification obtained in a radio circuit or a component of the circuit. It is measured as a direct ratio or logarithmically. In radar, there are two general usages of the term: (a) antenna gain, or a gain factor, is the ratio of the power transmitted along the beam axis to that of an isotropic radiator transmitting the same total power; and (b) receiver gain, or video gain, measures how much a receiver amplifies an incoming signal.
ii. A general term for the increase in signal power after transmission from one point to another. Gain is usually expressed in decibels and is widely used to denote transducer gain.
