The power gain of an electrical network is the ratio of an output power to an input power. Unlike other signal gains, such as voltage and current gain, "power gain" may be ambiguous as the meaning of terms "input power" and "output power" is not always clear. Three important power gains are operating power gain, transducer power gain and available power gain. Note that all these definitions of power gains employ the use of average (as oppose of instantaneous) power quantities and therefore the term "average" is often suppressed, which can be confusing at occasions.

Famous quotes containing the words power and/or gain:
“we are laid asleep
In body, and become a living soul:
While with an eye made quiet by the power
Of harmony, and the deep power of joy,
We see into the life of things.”
—William Wordsworth (1770–1850)
“If goodness were only a theory, it were a pity it should be lost to the world. There are a number of things, the idea of which is a clear gain to the mind. Let people, for instance, rail at friendship, genius, freedom, as long as they will—the very names of these despised qualities are better than anything else that could be substituted for them, and embalm even the most envenomed satire against them.”
—William Hazlitt (1778–1830)
