In communications media, channel attenuation is often expressed in decibels (dB) for each device distance. Attenuation of zero decibels implies that the signal is passed with out reduction; three decibels implies that the strength of the sign decreases by one-half. The plot of channel attenuation because the sign frequency is assorted is called the attenuation spectrum, although the average attenuation more than the whole frequency range of a transmitted sign is outlined since the attenuation coefficient.
