24. An asynchronous signal that is synchronized by a D flip-flop and goes temporarily metastable has less of a chance of causing a problem if: (a) the hold time of the D flip-flop is increased (b) the setup time of the D flip-flop is increased (c) the asynchronous signal changes infrequently (d) the synchronizing clock is high frequency 25. Why do we care about metastability for a doubled flopped asynchronous input to a synchronous digital circuit? (a) may cause hazards (b) may limit maximum operating frequency (c) may increase clock skew (d) may cause false clock edges 26. Why is it important to synchronously remove a reset signal? (a) reduce power consumption (b) avoid hold time violations (c) reduce metastability MTBF (d) reduce reset circuitry
