C. In a high-quality coaxial cable, the power drops by a factor of 10 approximately every 3 km. If the original signal power is 0.55 W (=5.5 x 10-?), how far will a signal
be transmitted before the power is attenuated to 55 uW?
Include a table showing the signal power in W) versus distance in 3 km intervals
(like Table 1.2 in Section 1.4.4) as part of your answer.
If optical fibre is used instead of the coaxial cable, briefly explain how you would
expect the above calculated distance value to change (see Section 1.4.4).
You are not required to include another table in answering this last part of part c.
