Part A We presented four impairments to physical transmission of signals – attenuation, noise, attenuation distortion, and delay distortion. How will these affect the guided media of copper wires and optical fibre cable, and wireless media? Suggest some techniques that are used at the physical layer to counteract these effects (that is ignore techniques like error detection and correction used at higher layers). Part B Consider again the above three media, but in this case how does sec …
