Attenuation, английский
- The decrease in magnitude of a signal, as it travels through a medium. used to describe signal loss in a transmission system. measured in decibels (db).
- Поглощение
- Зависимость снижения мощности сигнала от расстояния. для оптоволоконных кабелей обычно выражается в дб/км
- In general terms, a reduction in signal strength.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or
- The difference between transmitted and received power due to loss through equipment, lines, or other transmission devices; usually expressed in decibels. the loss in power of electromagnetic signals between transmission and reception points.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or an electric system. it is measured in decibels (db).
- The loss of optical power, whether caused intrinsically (absorption, scattering, microbends, etc.), or extrinsically by components (connectors, splices, splitters, etc)
- The decrease in radiation energy (power) as a beam passes through an absorbing or scattering medium.
- Reduction of signal magnitude, or loss, normally measured in decibels. fiber attenuation is normally measured per unit length in decibels per kilometer. the decrease in signal strength along a fiber optic waveguide caused by absorption and scattering. attenuation is usually expressed in db/km.
- A reduction in the effect or strength of something such as a virus, either because of environmental conditions or as a result of a laboratory procedure
- Ослабление
- Ослабление (затухание). уменьшение количества радиации при ее прохождении через вещество в результате всех видов взаимодействия с этим веществом. ослабление обычно не связано с уменьшением геометрических размеров (мос, 5). ослабление солнечной радиации — потеря энергии световым лучом при его прохождении через атмосферу земли. потеря энергии обусловлена рассеянием света молекулами воздуха, селективной абсорбцией молекулами определенных веществ и рассеянием света аэрозолями (вмо).
- The weakening of a transmitted signal, such as the distortion of a digital signal or the reduction in amplitude of an electrical signal. attenuation is usually measured in decibels and is sometimes desirable, as when signal strength is reduced electronically, for example, by a radio volume control, to prevent overloading.
- The weakening of a transmitted signal, such as the reduction in the brightness of light, as it travels farther from its source.
- Regulatory system of prokaryotes whereby secondary stem-loop structures formed within the 5’ end of an mrna being transcribed determine both if transcription to complete the synthesis of this mrna will occur and if this mrna will be used for translation
- Decrease in transmitted energy intensity over distance. the loss may be due to absorption, scattering, reflection, leakage, beam divergence, or other material effects.
- Снижение интенсивности передаваемой энергии на расстоянии. потери могут быть вызваны поглощением, рассеянием, отражением, утечкой, расходимостью луча или другими материальными эффектами.
- Decrease in signal magnitude during energy transmission from one point to another. this loss may be caused by absorption, reflection, scattering of energy or other material characteristics or may be caused by an electronic or optical device such as an attenuator.1
- (1) decrease in energy or signal magnitude in transmission from one point to another. can be expressed in decibels or as a scalar ratio of the input magnitude to the output magnitude.16 (2) change in signal strength caused by an electronic device such as an attenuator. (3) decrease in intensity caused by absorption, leakage, reflection, scattering or other material characteristics. see also neper.
- (1) decrease in acoustic energy over distance. this loss may be caused by absorption, leakage, reflection, scattering or other material characteristics. (2) decrease in signal amplitude caused by acoustic energy loss or by an electronic device such as an attenuator.10,16,21
