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 code’s 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)
“You may say a cat uses good grammar. Well, a cat does—but you let a cat get excited once; you let a cat get to pulling fur with another cat on a shed, nights, and you’ll hear grammar that will give you the lockjaw. Ignorant people think it’s the noise which fighting cats make that is so aggravating, but it ain’t so; it’s the sickening grammar they use.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Nothing is quite so wretchedly corrupt as an aristocracy which has lost its power but kept its wealth and which still has endless leisure to devote to nothing but banal enjoyments. All its great thoughts and passionate energy are things of the past, and nothing but a host of petty, gnawing vices now cling to it like worms to a corpse.”
—Alexis de Tocqueville (1805–1859)
