Signal Attenuation

Total loss over a cable or transmission line run, from a per-unit-length attenuation rate (as published on a cable's datasheet): Loss(dB) = rate(dB/100m) × length/100, then received power Prx = Ptx − Loss(dB).

Ptx Prx cable/line, length L
Signal amplitude decreases steadily with distance along the cable.
