<CommuniCations> 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.
