Discussion
_________ is a type of transmission impairment in which the signal looses strength due to the resistance of the transmission medium.
Answer: A
The impairment in which the signal loses strength because of the resistance of the transmission medium is attenuation. Energy is converted to heat as the signal travels, so its amplitude falls with distance, and amplifiers or repeaters are used to restore it.
Distortion is a change in the shape of the signal, noise is unwanted energy added to the signal, and the decibel is only a unit used to measure gain or loss.
