Question

Advantage and disadvantage of jk flip flop

Answer 1

Advantages

1. Among the basic flip-flops the J-K flip-flop is the most versatile.

2. It has two inputs which are labelled as J and K. If J and K are not the same then the output Q takes the value of J at the next clock edge.

3. It is an improved variation of the SR Flipflop.

Disadvantages

1. Spikes can appear on the output.

2. An unstable state occurs when both J and K inputs are logic '0'

Answer 2

Advantages:

# If both inputs J and K have high inputs assigned to them, then the output Q toggles between the high and two states. As a result, there are no ambiguous states and the JK flip-flop can operate as a set/reset flip-flop.

# When the two inputs are tied together, the JK flip-flop can act as a T flip-flop that is widely used in binary counters.

Disadvantage:

# When both the inputs and clock pulse signal are at level 1 after the output is complemented once, output transmission will start getting repeated and continuous. This results in a raised condition.
