Transcribed Image Text:Attenuation, distortion, and noise contribute to transmission impairment. What is the
solution, or how can these causes be improved?
Expert Solution
Step 1
Attenuation
-> The weakening of the signal over the transmission line is what causes attenuation. To address the issue:
The transmission line signal can be strengthened by using an amplifier or repeater.
Keep the signal at a higher level to prevent errors from occurring.
As an amplifier can magnify higher frequencies much more than lower ones, we can also employ an equaliser to reduce attenuation across the frequency band.
