Single parity check code
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 waveform.

Calculate the dc voltage before and after encoding
: Write the 30-bit sequence that will be transmitted if the encoder receives the bit sequence 00000316.

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..
