What happens to the output if J-K 1 in J-K flip-flop?
However, if both the J and K inputs are HIGH at logic “1” (J = K = 1), when the clock input goes HIGH, the circuit will “toggle” as its outputs switch and change state complementing each other. This results in the JK flip-flop acting more like a T-type toggle flip-flop when both terminals are “HIGH”.
What is the output of a J-K flip-flop?
The J-K flip-flop is the most versatile of the basic flip-flops. It has the input- following character of the clocked D flip-flop but has two inputs,traditionally labeled J and K. If J and K are different then the output Q takes the value of J at the next clock edge.
How can flip-flop be converted to J-K flip-flop?
The conversion of flip-flops to a JK flip-flop is to cross connect the Q and Q outputs with the S and R inputs through additional 3-input AND gates as shown. If the J and K inputs are both HIGH, logic “1” then the Q output will change state (Toggle) for as long as the clock input, (CLK) is HIGH.
What is an indeterminate condition in an Srflip flop?
When the pulse is removed, the state of the flip-flop is indeterminate, i.e., either state may result, depending on whether the set or reset input of the flip-flop remains a 1 longer than the transition to 0 at the end of the pulse.
What is the short coming of J-K flip-flop?
The JK flip flop is a universal flip flop having two inputs ‘J’ and ‘K’. In SR flip flop, the ‘S’ and ‘R’ are the shortened abbreviated letters for Set and Reset, but J and K are not. The J and K are themselves autonomous letters which are chosen to distinguish the flip flop design from other types.
Why is it called J-K flip-flop?
The JK flip flop was named after Jack Kilby, the Texas Instruments engineer that invented the integrated circuit in 1958. The modified RS circuit that eliminated race conditions was named JK in his honor.

What are the disadvantages of JK flip flop?
JK flip-flop has a drawback of timing problem known as “RACE”. The condition of RACE arises if the output Q changes its state before the timing pulse of the clock input has time to go in OFF state. The timing pulse period (T) should be kept as short as possible to avoid the problem of timing.
