For the following assume that no data compression is done, Ask an Expert

Engineering

For the following, assume that no data compression is done; this would in practice almost never be the case. For (a)-(c), calculate the bandwidth necessary for transmitting in real time:

(a) Video at a resolution of 640 × 480, 3 bytes/pixel, 30 frames/second.

(b) 160 × 120 video, 1 byte/pixel, 5 frames/second.

(d) Assume a fax transmits an 8 × 10-inch black-and-white image at a resolution of 72 pixels per inch. How long would this take over a 14.4-Kbps modem?
