Attenuation (Beer Brewing)

The degree to which the sugars in the wort have been converted to alcohol and CO2. See also: apparent attenuation, actual attenuation.

Attenuation (Cellular)

The loss of signal energy due to absorption, reflection, or diffusion during transmission.

Attenuation (Climatology)

Any decrease in amplitude, density, or energy as result of an effect such as scattering, absorption, or friction. In physical meteorology, a reduction in radiation flow, especially solar radiation by atmospheric gases and aerosols. In radar meteorology, the decrease in the magnitude of current, voltage, power, or intensity of a signal in transmission between points. Attenuation may be caused by interference such as rain or clouds.

Attenuation (Computer Technology)

Attenuation is the loss of signal strength which begins to occur as the signal travels further along a copper cable.

Attenuation (Earthquake)

When you throw a pebble in a pond, it makes waves on the surface that move out from the place where the pebble entered the water. The waves are largest where they are formed and gradually get smaller as they move away. This decrease in size, or amplitude, of the waves is called attenuation.

Attenuation (Electric Power)

(l) The ratio of the input to output power levels in a network (transmission line) when it is excited by a matched source and terminated in a matched load. (2) Power loss in an electrical system.

Attenuation (Environment)

The process by which a compound is reduced in concentration over time, through absorption, adsorption, degradation, dilution, and/or transformation. an also be the decrease with distance of sight caused by attenuation of light by particulate pollution.

Attenuation (Fiber Optics)

The loss of signal strength (optical power) during transmission between two points. It expresses the total loss of an optical system, measured in decibels per kilometer (dB/km) at specific wavelengths. See "intrinsic loss" and "extrinsic loss" in this glossary.

Attenuation (Hunting)

The loss or dissipation of wave energy, resulting in a reduction of wave height (amplitude).

Attenuation (Import Cars)

The decrease in the strength of a signal as it passes through a control system.

Attenuation (Metal)

The fractional decrease of the intensity of an energy flux, including the reduction of intensity resulting from geometrical spreading, absorption, and scattering.

Attenuation (Microbiology)

A form of gene regulation wherein termination of transcription is controlled to regulate overall levels of gene expression.

Attenuation (Natural Gas)

See SOUND ATTENUATION.

Attenuation (Video)

This refers to signal loss in a transmission system

Attenuation (Video Projector)

The decrease in the magnitude of a signal. A decrease in signal voltage during its transmission from one point to another.
