(Askeri) attenuation
A weakening in the virulence of a pathogen or other microorganism
A reduction in the level of some property with distance, especially the amplitude of a wave or the strength of a signal
{n} a making thin or slender
The tapering of a leaf etc to a fine point
Attenuation (AT) is a general term used to denote the decrease in power between that transmitted and that received due to loss through equipment, lines, or other transmission devices It is usually expressed as a ratio in dB (decibel)
loss of a substance as it is deflected, fragmented, or absorbed For example, solar irradiance attenuates as it passes through the atmosphere to the surface of the earth
the property of something that has been weakened or reduced in thickness or density weakening in force or intensity; "attenuation in the volume of the sound
The decrease in magnitude of current, voltage, or power of a signal in transmission between two points May be expressed in decibels
The decrease of signal strength as it travels through the cable or device, measured in decibels
is the decrease in signal strength as the signal travels through any medium such as a cable
The process by which a compound is reduced in concentration over time, through adsorption, degradation, dilution, and/or transformation Radiologically, it is the reduction of the intensity of radiation upon passage through a medium The attenuation is caused by absorption and scattering
Decrease in magnitude of power of a signal in transmission between points When used for expressing the total loss of an optical system, attenuation is measured in decibels (dB) at a specific wavelength
(communications usage) Signal strength loss between the transmission and reception points For example: Heavy rainstorms can cause microwave signals to seem to fade, i e , to attenuate, as the rainstorm passes through an area (See also: Rain Fade)
{i} reduction; weakening; decrease; diminution; being weakened; weakening of a signal as the length of a network cable increases (Computers)
A loss of signal strength in a lightwave, electrical or radio signal usually related to the distance the signal must travel (e g fiber optic transmission must be regenerated approx every 30 miles) Fiber optic attenuation is caused by transparency of the fiber, bending the fiber at too small of a radius, nicks in the fiber, splices, poor fiber terminals, FOTs, etc (See EDOA), Electrical attenuation is caused by the resistance of the conductor, poor (corroded) connections, poor shielding, induction, RFI, etc Radio signal attenuation may be due to atmospheric conditions, 1 spots, antenna design / positioning, obstacles, etc
1 Atmospheric attenuation: the simulation of the atmospheric attenuation from the object to the viewer which affects both the illumination strength and color The attenuated illumination is computed by where s is a scale factor ranging from 0 to 1, is the illumination and is the depth-cue color 2 Light source attenuation: a factor in the illumination equation used to simulate surface illumination depending on how far the surface is from the light source It is defined by: where is the distance between the source light and the surface, and and are user defined constants associated with the light source
A fabrication process in which a material is stretched out into a thin shape
The decrease in magnitude of a signal as it travels through any transmission medium such as a cable or optical fiber Measured in dB per unit of length
The decrease in magnitude of power of a signal in transmission between points For example, in fiber, expresses the total loss of an optical fiber consisting of the ratio of light output to light input Attenuation is measured in decibels (fiber or copper) per kilometer (dB/km) at a specific wavelength or frequency The lower the number, the better Typical multimode wavelengths are 850 - 1300 nanometers (nm) and singlemode are at 1300 - 1550 nm Copper is now characterized up to 350 MHz plus
the property of something that has been weakened or reduced in thickness or density
