2.
A horizontal output stage is cutoff for retrace and 40% of trace. If time for each horizontal line is 64 μs and retrace time is 12 μs, the transistor is conducting for about
Answer: Option
Explanation:
Total time for each horizontal line = 
.
Time for trace = 64 - 12 = 52 μs.
Time for which transistor is not conducting = 12 + 0.4 x 52 = 32.8 ms.
Time for which transistor is conducting = 64 - 32.8 = 31 μs.
