  1. 1. FLIP FLOP
  2. 2. Introduction aboutFlip FlopFarwa Tahira11014156-018
  3. 3. Logic circuits are classified into two groups:Combinational logic circuitsSequential logic circuitsBasic buildingblocks include:Basic building blocksinclude FLIP-FLOPS:LOGIC CIRCUITSLogic gates make decisionsFlip Flops have memory
  4. 4. FLIP FLOP Flip-flops and latches are used as data storage elements. Flip-flops can be either simple or clocked the simple ones are commonlycalled latches. The word latch is mainly used for storage elements,while clocked devices are described as flip-flops

  14. 14. WHAT IS A JK FLIP-FLOP? A flip-flop is a circuit that has two stablestates and can be used to store stateinformation. The flip-flop can be made to change stateby signals applied to one or more controlinputs and will have one or two outputs.

  18. 18. T Flip FlopAdeel Zafar11014156-038
  19. 19. T (TOGGLE) FLIP FLOPDefinationToggle flip-flop. The output alternates with each input signal change. Tosimulate a T flip-flop, you can simply connect a D flip-flops complementaryoutput Q with its inputSymbol
  20. 20. T (TOGGLE) FLIP FLOPT Flip Flop Characteristic TableT Q Q+ Operation0 0 0 Hold0 1 1 Hold1 0 1 Toggle1 1 0 ToggleThe T flip flop characteristic table has 3columns. The first column is the value of T,a control input. The second column isthe current state, that is the current valuebeing output by Q.
