Detailed Solution
Download Solution PDFThe correct answer is: 1) Edge-triggering responds to the transition of the clock, while level-triggering responds to the level of the clock.
Triggering methods of flip-flop:
1.) Edge Triggering:
- In a sequential circuit, if the output changes when the signal transits from a high level to a low level or from a low level to a high level, we call it edge triggering.
- Here, the edge that changes the voltage from the low level to the high level is called the positive edge.
- And, the edge that changes the voltage from the high level to the low level is called the negative edge.
2.) Level Triggering:
- In the sequential circuit, if the output changes during the high voltage period or low voltage period, it is called level triggering.
- The output of the circuit is high for a positive level and low for a negative level.
