Semiconductors
a. Briefly describe "semiconductor doping."
b. Briefly compare Ge, Si, and GaAs. Which can be used for ery-low-noise amplifiers? And for light-emitting devices? Why is Si preferred whenever possible?

How many information bits are conveyed by each encoder
: Suppose that the following sequence of symbols must be transmitted: (-2, +2), (0, 0), (+2, -2), (0, 0), (-2, +2), (0, 0), . . . . Draw the corresponding waveform in each pair of wires (use the clock period, T, as your time unit).

Calculate and explain the resulting symbol rate
: Suppose that the following sequence of symbols is allowed and must be transmitted: (-2, -1, +1, +2), (0, +1, -1, 0), (-2, -1, +1, +2), (0, +1, -1, 0), . . . . Draw the corresponding waveform in each pair of wires using the clock period, T, of part..

Draw the corresponding 33-bit waveform
: Assume that the character string "Hi!", encoded using the ASCII code, must be transmitted using an asynchronous transmission protocol similar to that seen in Figure 7.2, which includes start, stop, and parity bits. Draw the corresponding 33-bit wa..

Why are the individual encoders called rsc
: As we saw, turbo codes are quite new (1993). Even though they could outperform all codes in use at that time, why were they overshadowed only a few years later?
