Which of the following flip-flops is free from race around condition?
Master slave JK flip-flops is free from race around condition.
During high clock when ever applied input changes the output also changes. But in JK flipflop when j=k=1 , without any change in the input the output changes , this condition is called as race around condition.
The circuit accepts input data when the clock signal is “HIGH”, and passes the data to the output on the falling-edge of the clock signal. In other words, the Master-Slave JK Flip flop is a “Synchronous” device as it only passes data with the timing of the clock signal.
JK flip flop is most versatile flip flop and most commonly used when descrete devices are used to implement arbitary state machine.
