a) The signal power for a particular class of network wiring is 2,898dB, and the noise rating at that particular signal strength at 100MHz is 40dB. Find the signalto- noise ratio for this conductor.
b) Suppose the noise rating for the network wiring in part a is 0.32dB and the noise rating is 35dB when a 200MHz signal is transmitted. What is the signal strength
