    The uncertainty in the state of and SR flip flop When S=R=1 can be eliminated by converting it into a JK flip flop.

    thanks.how to convert it sr to jk ? to solve the problem of invalid state for both s=r=1 ?

    i got it. but some confusion in design i mean in gates, its NOR or NAND like that ?
    one more is these design is correct or not ?

    sr

    sr flop flop

    jk

    jk flop flop by using sr flop

    is this conversion correct ?

    if in jk both j and k is high, then it goes to toggle. it means output will be the compliment of the previous state right ?
    pls reply

    The conversion is correct( I have referred my books) .

    @andeepbangalore the output is Q*

    @andeepbangalore the output is Q*
    Q* is nothing but the same rite i mean , out put is compliment of the previous output ?

    wave

    in this figure i found that , when j = k =1 then the output is toggle i mean will be compliment for previous output , is this correct ?
  • aarthivg

    yes. Right.
    anyway @ #-Link-Snipped-# can conform it once again

    In SR flip flop when we have S=1 R=1 we get intermediate state. In JK flip flop we eliminate the intermediate state by complement Q- ( J=1,K=1 Q+ = (Q-)') so we can say that JK flip flop is refinement of SR flip flop.

    Thanks in advance
