| 41. | As applied to a flip flop the word edge triggered's means |
|||||||
Answer: Option A Explanation: Edge triggering means the instant when clock transition occurs. |
| 42. | A NOR gate is a combination of |
|||||||
Answer: Option C Explanation: OR and NOT = NOR. |
| 43. | The 2's complement representation of - 17 is |
|||||||
Answer: Option B Explanation: (17)10 = (10001)2 = (-17)10 = 1's complement of (17)2 + 1
the MSB is 0, hence (-17)2 cannot represented in 2's complement representation with 5 bit, therefore (-17) in 2's complement is simply (10001)2 = (17)10 . |
| 44. | TTL inverter has |
|||||||
Answer: Option B Explanation: Data input and control input. |
| 45. | 4 bit ripple counter and 4 bit synchronous counter are made using flip-flop having a propagation delay of 10 ns each. If the worst case delay in the ripple counter and the synchronous counter be R and S respectively, then |
|||||||
Answer: Option B Explanation: In synchronous counter time delay is constant while in Ripple it is additive. |
