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:
“Come unto me, [Krokowski] was saying, though not in those words, come unto me, all ye who are weary and heavy-laden.... He spoke of secret suffering, of shame and sorrow, of the redeeming power of the analytic. He advocated the bringing of light into the unconscious mind.”
—Thomas Mann (18751955)
“...if you are to gain any great amount of good from the world, you must attain a passive condition of mind. ...it is never to be forgotten that it is the rest of the world and not you that holds the great share of the worlds wealth, and that you must allow yourself to be acted upon by the world, if you would become a sharer in the gain of all the ages to your own infinite advantage.”
—Anna C. Brackett (18361911)
