Description : What is edge-triggered flip-flop?
Last Answer : The problem of race around condition can solved by edge triggering flip flop. The term edge triggering means that the flip-flop changes state either at the positive ... negative edge of the clock pulse and it is sensitive to its inputs only at this transition of the clock.
Description : Define race around condition.
Last Answer : In JK flip-flop output is fed back to the input. Therefore change in the output results change in the input. Due to this in the positive half of the clock pulse if both J and K are high then output toggles continuously. This condition iscalled ‘race around condition’.

Last Answer : When K input is low and J input is high the Q output of flip-flop is set. When K input is high and J input is low the Q output of flip-flop is reset. When both the inputs ... are high it is possible to set or reset the flip-flop (ie) the output toggle on the next positive clock edge.
Description : What is the operation of D flip-flop?
Last Answer : In D flip-flop during the occurrence of clock pulse if D=1, the output Q is set and if D=0, the output is reset.
