Problem 2:12 points It is desired to send a sequence of computer screen images over an optical fiber. The screen is 400x 800 pixels, each pixel being 24 bits. There are 26 screen images per second for 30 seconds. How much bandwidth is needed, and how many microns of wavelength are needed for this band at 1.15 microns? 0 Problem 3:8 points Radio antennas often work best when the diameter of the antenna is equal to the wavelength of the radio wave. Reasonable antennas range from 5.00 cm to 2.74 meters in diameter. What frequency range does this cover? 7 Problem 4:9 Points Calculate the end-to-end transit time for a packet for GEO (altitude: 35,600 km), MEO (altitude: 18,400 km) and LEO (altitude: 760 km) satellites Problem 5:12 Points A regional telephone company had 2.6 million subscribers. Each of their telephones is connected to a central office by a copper twisted pair. The average length of these twisted pairs is 6.4 km. How much is the copper in the local loops worth? Assume that the cross section of each strand is a circle 1.1 mm in diameter, the density of copper is 8.7 grams/cmA3, and that copper sells for $10.50 per kilogram. 9
