Which of the following flip-flops is free from race condition ?
Master-slave JK flip-flop
A level-triggered JK or T flip-flop suffers race-around: with J = K = 1 the output keeps toggling while the clock is high.
In a master-slave JK flip-flop the master responds while the clock is high and the slave copies it only when the clock goes low.
The output changes only once per clock pulse, so the race-around condition is removed.
Hence, Master-slave JK flip-flop.
