Solution
The correct option is D Master slave JK flip-flop
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.
