|What is the meaning of inputs of j k flipflop cycle?|
|Sundar said: (Oct 3, 2011)|
|Assume J=0 and K=1
When cycle it, it becomes as J=1 and K=0.
|Anaya said: (Oct 14, 2011)|
|Then there will be change how answer is no change.|

|@Sundar clue is correct but small changes.
After one cycle the value of each input comes to the same value
ex: Assume J=0 and K=1.
After 1 cycle, it becomes as J=0->1->0(1 cycle complete) and K=1->0->1(1 cycle complete).
So answer is B. not change o/p.

|@Ravi sinha tabe is right. When they form in cycle they form in 1 & 0 so output become no change.|

|What is meant by toggle?|
|Ravikanth said: (Nov 6, 2014)|
Toggle means complement.

|Toggle condition when the J-K flip flop receives the both the inputs as high and clock is also in rise edge the output of the flip flop will be changes to 0 and 1.
It will not be constant constant output for every clock cycle it will race in between 1/0/1/0.

|When it cycles like j=1and k=0 then how it becomes no change, It becomes set condition right?|

|Cycle = 2 x toggle.|
