For data transmitted over twisted-pair cable, you have these characteristics: A signal s power on the channel is 75 dB, signal attenuation is 5 dB per 100 meters, and average noise power on the cable is 0.1 dB per meter. Answer the following questions:
• What 's the S/N ratio at the end of a 50-meter channel?
• What 's the S/N ratio at the end of a 1-kilometer channel?
• What 's the maximum channel length if the receiving device requires at least 20 dB of S/N ratio for reliable operation?
• What 's the S/N ratio at the end of a 50-meter channel?
