What is a signal attenuation?

It is specified in decibel (Db). The attenuation (A) depends not only on the length of the transmission path, but also on the transmission frequency, the material of the transfer medium as well as the physical ambient conditions. The degree of the attenuation can be calculated for signal voltages (U) as well as for signal currents (I).

What does attenuation mean in physics?

An attenuator is a two-port resistive network. It is used to reduce the power being supplied to a device. The attenuation is the size of this reduction in power expressed in decibels. What is attenuation in decibels? Attenuation is measure in decibels because attenuation is a unitless but very small number expressed in a logarithmic scale.
