As a part of
liberal international relations theory, absolute gain is a term used to describe how (primarily) states will act in the international community. The theory says that international actors will look at the total effect of a decision on the state or organization and act accordingly. The international actor's interests not only include power ratios but also encompass the economic and cultural effects of an action as well. The theory is also interrelated with a
non-zero-sum game which proposes that through use of
comparative advantage, all states who engage in peaceful relations and trade can expand wealth.

1. Of an
antenna , for a given direction and
polarization , the ratio of (a) the
power that would be required at the
input of an ideal
isotropic radiator to (b) the power actually supplied to the given antenna, to produce the same
radiation intensity in the
far-field region . Note 1: If no direction is given, the absolute
gain of an antenna corresponds to the direction of maximum
effective radiated power . Note 2: Absolute gain is usually expressed in
dB . (
188 ) Synonym isotropic gain. 2. Of a device, the ratio of (a) the
signal level at the
output of the device to (b) that of its input under a specified
set of operating conditions. Note 1: Examples of absolute gain are no-
load gain, full-load gain, and small-signal gain. Note 2: Absolute gain is usually expressed in dB. (
