Operations of J-K Flip Flop

Given Below is the Operations of J-K Flip Flop

  • Case 1 (PR=CLR=0 ):This condition is in its invalid state.
  • Case 2 (PR=0 and CLR=1):The PR is activated which means the output in the Q is set to 1. Therefore, the flip flop is in the set state.
  • Case 3 (PR=1 and CLR=0):The CLR is activated which means the output in the Q’ is set to 1. Therefore, the flip flop is in the reset state.
  • Case 4 (PR=CLR=1):In this condition the flip flop works in its normal way whereas the PR and CLR gets deactivated.

Race Around Condition in J-K Flip Flop

When the J and K both are set to 1, the input remains high for a longer duration of time, then the output keeps on toggling. Toggle means that switching in the output instantly i.e. Q=0, Q’=1 will immediately change to Q=1 and Q’=0 and this continuation keeps on changing. This change in output leads to race around condition.

Characteristics Equation for JK Flip Flop

QN+1 = JQ’N + K’QN

What is a Flip-Flop?

The flip-flop is a circuit that maintains a state until directed by input to change the state. A basic flip-flop can be constructed using four-NAND or four-NOR gates. Flip-flop is popularly known as the basic digital memory circuit. It has its two states as logic 1(High) and logic 0(low) states. A flip flop is a sequential circuit which consist of single binary state of information or data. The digital circuit is a flip flop which has two outputs and are of opposite states. It is also known as a Bistable Multivibrator....

S-R Flip Flop

In the flip flop, with the help of preset and clear when the power is switched ON, the states of the circuit keeps on changing, that is it is uncertain. It may come to set(Q=1) or reset(Q’=0) state. In many applications, it is desired to initially set or reset the flip flop that is the initial state of the flip flop that needs to be assigned. This thing is accomplished by the preset(PR) and the clear(CLR)....
