For data is transmitted over twisted-pair cable, you have these characteristics: A signal's power on the channel is 60 dB, signal attenuation is 2 dB per 100 meters, and average noise power on the cable is 0.15 dB per meter. Answer the following questions: What's the S/N ratio at the end of a 60-meter channel? What's the S/N ratio at the end of a 1.5-kilometer channel? What's the maximum channel length if the receiving device requires at least 25 dB of S/N ratio for reliable operation?
