Definition of "Attenuation" |
Loss of signal power or amplitude suffered during its transmission through a medium. / The decrease in magnitude of a signal as it travels through any transmitting medium, such as a cable or circuitry. The ability of a filter circuit to reduce the amplitude of unwanted frequencies to a level below that of the desired output frequency.

The rate of diminution of average power with respect to distance along a transmission path. / Attenuation is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water. / Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances. The extent of attenuation is usually expressed in units called decibels. / Die is a rectangular piece of a semiconductor wafer. / the exponential decrease with distance, in the amplitude of an electric signal traveling along a very long transmission line due to losses in the supporting medium. In electromagnetic systems attenuation is due to conductor and dielectric losses. In fiber optic systems attenuation arises from intrinsic material properties (absorption and Rayleigh scattering) and from waveguide properties such as bending, microbending,splices, and connectors. |
