Explanation:
Detailed explanation-1: -Three causes of impairment are attenuation, distortion, and noise. Attenuation means a loss of energy. When a signal, simple or composite, travels through a medium, it loses some of its energy in overcoming the resistance of the medium.
Detailed explanation-2: -Distortion is a type of transmission impairment in which the signal loses strength due to the different propagation speeds of each frequency that makes up the signal.
