1. As we will learn in the next chapter, one means of transmitting bits over traditional telephone systems is to convert the bit patterns into sound, transfer the sound over the telephone lines, and then convert the sound back into bit patterns. Such techniques are limited to transfer rates of 57.6 Kbps. Is this sufficient for teleconferencing if the video is compressed using MPEG?
2. Encode the following sentences in ASCII using even parity by adding a parity bit at the high-order end of each character code:
a. Does 100/5 = 20?
b. The total cost is $7.25.
