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 flop flop

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

@ #-Link-Snipped-#

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

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

@andeepbangalore the output is Q*

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 ?

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
