Explanation:
Detailed explanation-1: -Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances.
Detailed explanation-2: -Three types of attenuation exist: deliberate, environmental, and automatic attenuations.
Detailed explanation-3: -Signal attenuation is the reduction or loss of communication signal strength during transmission, which is the mode of transferring data, such as an email or phone call. A signal refers to the current that transmits data from one network to another.
