If we need to download text documents at rate of 1000 pages per minute. Each page has 24 lines with 80 characters per line. Find required bit rate.
1
2
3
4
Solution
Characters per page = 24 × 80 = 1920
Assume 1 character = 8 bits
Bits per page = 1920 × 8 = 15360 bits
1000 pages/min = 15360000 bits/min
Bits/sec = 15360000 / 60 = 256000 bps
= 0.256 Mbps
