Exercise #3

1. 600 x 1,048,576 = 5,033,164,800 bits = 5Gb
2. Data

1,000 mega x (9x6) lines x (6.5 x 10) x 8 bits/char = 28.1Mb

Images:

100 x ( 1024 x 768 x 8) =629.1Mbits

Audio:

30min x 60sec/min x 16,000 samples/sec x 6 bits/sample = 172,800,000 = 172.8 Mb

Total is 830Mb = 5,000/830 = M6 volume per cd

3. 830 Mb/1.544 Mbps = 537.6 second = 9 minutes
4. Data: 28.1/ 3 = 9.4 Mb

Image: 629.1/10=62.9Mb

Audio: 172.8/86.4 Mb

Total: 158.7 Mb are about 32 volume on a CD transmission time = 158.7/1.544

= 103 secs = 1 min 43 secs.
