In an optical ﬁbre, the power drops by a factor of 10 approximately every 30 km. If the transmit power is 0.35 W, how far will a signal be transmitted before the power is attenuated to 350 μW? As part of your answer, include a table showing the signal power (in W) vs. distance in 30 km intervals (like Table 1.2 in Section 1.4.4). If a high-quality coaxial cable (LDF5-50A) operating at 200 Mbps is used instead of an optical fibre, how would you expect the calculated distance value to change? Briefly explain your answer (see Section 1.4.4). You are not required to include another table.
The Transform 66 Outside the Beltway project, scheduled to be completed late 2022, is an expansion of the current highway that will provide new travel choices for drivers and hopefully congestion relief from the Capital Beltway (I-495) to Gainesville for a 22.5 mile stretch. This 22.5 mile stretch of I-66 will go through both Fairfax County and Prince William County. VDOT had team members from the project reach out through a phone survey for a random selection of 3,500 residents from both Fairfax County and Prince William County. One question asked on the survey was “Do you feel that the new I-66 Express Lanes will bring congestion relief?” Of the Fairfax County residents surveyed, 1,642 agreed they thought that the expansion will bring congestion relief while only 1,576 of the Prince William County residents surveyed agreed with the statement. 1) What is a possible confounding variable that might have introduced sampling bias intothe results of the survey?
