Problem
1. This chapter introduced a bipolar encoding scheme. What would be an example of a unipolar encoding scheme?
2. Megadome is a typical company with many users, local area networks, Internet access, and so on.
A user is working at home and connecting to the corporate e-mail system. Draw a linear chart of the connection from the user's personal computer at home to the corporate e-mail server on a local area network. On this linear chart, identify each form of data and signal. Are they analog? Digital? What data/signal conversions are taking place? Where are these conversions?
