S-set
R-reset
The nand gate variety of the SR flip-flop uses falsevalues to change state with, while the nor gate variety of the SR flip-flop uses true values to change state with.
no indeterminate state
when we provide two input as 1 or true or high out put of q and q' become same that violate the complement law.
---- The output of JK flip flop : J K Q(t+1) ---- 0 0 Q(t) 0 1 0 1 0 1 1 1 Q'(t) ---- the excitation table becomes: Q(t) Q(t+1) J K ---- 0 0 0 X 0 1 1 X 1 0 X 1 1 1 X 0 where X represents "don't care" ---- The out put of D flip Flop is: Q(t+1) D ---- 0 0 1 1 ---- Using MAP method, we find the function F 0 1 ---- 0 X 1 1 X ---- F= J+K' Therefore the JK flip flop becomes a D flip flop with an inverter paced just before the K entrance. I would have shown you more if this site allow graphics!
it can be eliminated by using not more than two level of gating. ANSWER: It can be eliminated by using grey code whereby there is only one transition of state before any other can occurs
J=SET K=RESET NOTE: JK FLIP FLOP IS NOTHING BUT AN ADVANCED VERSION OF THE SET-RESET()SR FLIP FLOP) SO, JK FLIP FLOP ALSO WORKS SOMEWHAT LIKE THE SR FLIP FLOP..... IS ACTUALLY THE LABORATORY TERM OF NUMBER 5 FLIP FLOP 5# J & K.
the advantage of JK flip-flop compared to clocked SR flip
Sr flip-flop is a bistable device with two states set and reset.
Sr flip-flop is a bistable device with two states set and reset.
An sr flip-flop can be converted into a jk flip-flop by changing the forbidden state in the sr flip-flop so that the out put toggles instead when the s=r=1.
The nand gate variety of the SR flip-flop uses falsevalues to change state with, while the nor gate variety of the SR flip-flop uses true values to change state with.
An SR flip-flop can be converted into an edge triggered flip-flop with preset and clear inputs by adding the clock and the asynchronous inputs.
no indeterminate state
flip-flop latches is 2. SR and JK latch
Hello The difference between an active low and an active high SR flip-flop is that with the active low SR flip-flop, the system is activated when the inputs to system are zeros while with the active high SR flip-flop, the system is activated when the inputs to the system are ones.
an unclocked flip-flop is the state to which the circuit settles after the inputs change. For a clocked device, the next state is the state after the clock pulse
