set reset flip flop
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.
draw a logic circuit of the clocked SR flip-flop using NOR gate
SR flip flop with clock enable .The output will change only when the clock is'1' and when the clock is '0' all the inputs will be ignored
