The Collaborative International Dictionary of English v.0.48 (gcide)

Attenuation \At*ten`u*a"tion\, n. [L. attenuatio: cf. F.
att['e]nuation.]
1. The act or process of making slender, or the state of
being slender; emaciation.
[1913 Webster]

2. The act of attenuating; the act of making thin or less
dense, or of rarefying, as fluids or gases.
[1913 Webster]

3. The process of weakening in intensity; diminution of
virulence; as, the attenuation of virus.
[1913 Webster]

The Free On-line Dictionary of Computing (foldoc)

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.
