Question

2.9 A common measure of transmission for digital data is the baud rate, defined as symbols (bits in our case) per second. As a minimum, transmission is accomplished in packets consisting of a start bit, a byte (8 bits) of information, and a stop bit. Using these facts, answer the following: (a)* How many seconds would it take to transmit a sequence of 500 images of size $1024 \times 1024$ pixels with 256 intensity levels using a 3 M-baud ($10^6$ bits/sec) baud modem? (This is a representative medium speed for a DSL (Digital Subscriber Line) residential line. (b) What would the time be using a 30 G-baud ($10^9$ bits/sec) modem? (This is a represen- tative medium speed for a commercial line.)
