1. Consider the following statements:
For a master-slave J-K flip-flop, the toggle frequency is the maximum clock frequency at which the flip-flop will toggle reliably.the data input must precede the clock triggering edge transition time by time minimum time.the data input must remain fixed for a given time after, the clock triggering edge transition time for reliable operation.propagation delay time is equal to the rise time and fall time of the data. Which of the above statements is/are correct?
