A common measure of transmission for digital data is the bau

A common measure of transmission for digital data is the baud rate, defined as the number of bits transmitted per second. Generally, 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: How many minutes would it take to transmit a 1024 Times 1024 image with 256 intensity levels using a 56k baud modem?

Solution

Total numbers of bits = 1024*1024 *[1+8+1] = 1048576 bits

Time required = total bits/baud modem used = 1048576/56k = 1048576/56000 = 187.25 sec = 3.1 minutes.
