See all on Wikipediahttps://en.wikipedia.org/wiki/AttenuationIn physics, attenuation or, in some contexts, extinction is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates. Hearing protectors help reduce

En électronique, l’atténuation ou affaiblissement est la diminution relative de la puissance d'un signal au cours de sa transmission. C'est la quantité par laquelle il faut multiplier la valeur du signal à la sortie pour obtenir celle à l'entrée de la section considérée.
L'atténuation, que ce soit dans une ligne de transmission ou dans un faisceau hertzien, est une grandeur importante dans les télécommunications, dont elle est un facteur limitatif. Ce concept …Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 9 mins

Attenuation can range between 0.33 and 0.80, but is usually 0.75. Because fermentation produces ethanol, which has a lower density than water (gravity of 0.787 at 25°C ), the apparent attenuation overestimates the actual percentage of sugars consumed. Brewers generally refer to this apparent attenuation when using the word without qualification, although the measurement of …

Feb 19, 2022 · attenuation ( countable and uncountable, plural attenuations ) A gradual diminishing of strength. ( physics) A reduction in the level of some property with distance, especially the amplitude of a wave or the strength of a signal. ( biology) A weakening in the virulence of a pathogen or other microorganism. ( botany) The tapering of a leaf etc ...

Attenuation — the falloff of a wave’s energy with distance — has three main causes: (1) transmission loss at interfaces because of reflection, diffraction, mode conversion, and scattering (Bowman, 1955); (2) geometric divergence effects as waves spread out from a source; and (3) absorption, which is the conversion of kinetic energy into ...

L'atténuation (en génétique) est un mécanisme de régulation de l'expression des gènes présent en particulier chez les bactéries.L'atténuation consiste en une terminaison prématurée de la transcription, en amont des gènes de structure. Il n'y a alors pas de synthèse d'un ARN messager complet et donc pas d'expression.. L'atténuation est observée dans un certain nombre …
