| Question 1 |
What is the bit rate of a video terminal unit with 80 characters/line, 8 bits/character and horizontal sweep time of lOOµs (including 20 µs of retrace time)?
| 8 Mbps | |
| 6.4 Mbps | |
| 0.8 Mbps | |
| 0.64 Mbps |
Question 1 Explanation:
Horizontal sweep time = 100µs
Total number of bits transmitted = 80 * 8 = 640 bits
Bit rate = (640 * 106)/100 = 6.4 Mbps
Total number of bits transmitted = 80 * 8 = 640 bits
Bit rate = (640 * 106)/100 = 6.4 Mbps
Correct Answer: B
Question 1 Explanation:
Horizontal sweep time = 100µs
Total number of bits transmitted = 80 * 8 = 640 bits
Bit rate = (640 * 106)/100 = 6.4 Mbps
Total number of bits transmitted = 80 * 8 = 640 bits
Bit rate = (640 * 106)/100 = 6.4 Mbps
