9a. What is Bandwidth of an Analog signal that have 5 frequencies 100, 300, 500, 800, 900 Hz. (5) 9b. What is the phase of an analog signal that is offset by 1/8 cycle. (5 pt.) 10. A TCP segment with 1560 bits of data and 150 bits of header is send to IP layer, where IP add another 150 bits of header, then is transmitted through two networks each of which uses 24-bit packet. If the destination node only has maximum packet size of 800 bits, show how many bits including headers are delivered? (10)
