In telecommunications, received noise power is a measure of noise in a receiver. For example, the received noise power might be:
- The calculated or measured noise power, within the bandwidth being used, at the receive end of a circuit, channel, link, or system.
- The absolute power of the noise measured or calculated at a receive point. The related bandwidth and the noise weighting must also be specified.
- The value of noise power, from all sources, measured at the line terminals of a telephone set's receiver.' Either flat weighting or some other specific amplitude-frequency characteristic or noise weighting characteristic must be associated with the measurement.

Famous quotes containing the words received, noise and/or power:
“How do we know, then, when a codes been cracked? ... when we are right? ... when do we know if we have even received a message? Why, naturally, when, upon one set of substitutions, sense emerges like the outline under a rubbing; when a single tentative construal leads to several; when all the sullen letters of the code cry TEAM! after YEA! has been, by several hands, uncovered.”
—William Gass (b. 1924)
“For twenty-five centuries, Western knowledge has tried to look upon the world. It has failed to understand that the world is not for the beholding. It is for hearing. It is not legible, but audible. Our science has always desired to monitor, measure, abstract, and castrate meaning, forgetting that life is full of noise and that death alone is silent: work noise, noise of man, and noise of beast. Noise bought, sold, or prohibited. Nothing essential happens in the absence of noise.”
—Jacques Attali (b. 1943)
“The delicious faces of children, the beauty of school-girls, the sweet seriousness of sixteen, the lofty air of well-born, well-bred boys, the passionate histories in the looks and manners of youth and early manhood, and the varied power in all that well-known company that escort us through life,we know how these forms thrill, paralyze, provoke, inspire, and enlarge us.”
—Ralph Waldo Emerson (18031882)
