attenuation : FOLDOC
attenuation
The progressive reduction in {amplitude} of a signal as it travels farther from the point of origin.
For example, an electric signal's amplitude reduces with distance due to electrical impedance. Attenuation is usually measured in {decibels} [per metre?].
Attenuation does not imply appreciable modification of the shape of the waveform (distortion), though as the signal amplitude falls the signal-to-noise ratio will also fall unless the channel itself is noise free or the signal is amplified at some intermediate point(s) along the channel.
