Take respect sir...You did an awesome work by opening this KZbin channel..You made this lecture about 3 years ago..But you are still gaining respect and you will also earn respect in future also..

But how, If J = S and K=R then JK AND SR flip-flops will act as same. And we know that this is not true.

[@PrateekBose05]

@@10_yogeshchandrapandey90 If you see without solving, then SR FF gives same result as JK FF except the 11 case, but SR FF does not care about 11 case as it is invalid.

[@10_yogeshchandrapandey90]

Yes, I am saying the same thing. Since, in case of SR FF the output is prohibited when S=R=1 but in that case, we will get result as toggle. It should be not like that.....

[@arnabjana2620]

For the confusing part in SR FF char. table when S=R=1, take Qn+1=don't care and put T or J,K values as don't care correspondingly, and solve for expression of J,K,T. That is the solution,what I found from all the comments and the k map.

[@ramavathravi2719]

you are the best teacher, there is no words about you.........Thank you sir

[@swarnalipal4658]

1)boolean expression :- J=S; K=R; In the combination of characteristic tab of SR with excitation tab of JK, when S=1, R=1, i.e invalid. therefore both J and K will be dont cares(X). This will give the above boolean expressions upon solving. 2) T=Qn'S+QnR.

[@rwitobaansheikh4275]

The answer is J=S and K=R is correct as the not used condition in SR ff is literally not used which means even if we get a different result with jk ff like toggle condition, we just don't use it because we assume it to be a SR ff.

stucked while converting t flip flop to sr flip flop

[@GoogleUser-ks9de]

We cannot fill the row for S = R = 1 in the excitation table for JK and T because it is an undefined condition! Also if we fill the row considering it to be a don't care condition then the resultant logic for JK to SR (J = S, K = R) will be JK itself because it will work for 11 input (J = 1, K = 1 => Race around/Toggle) which an SR does not!; and the resultant logic for T to SR (T = Q'S + QR) will also be JK because it will also work for 11 input (T = Q' + Q = 1 => Toggle) which an SR does not!

1. J=S and K=R. 2. T=QR'+Q'S

[@brandonyangeh602]

thanks very much sir...love you

[@Hurricoaster]

The first practice problem has a very interesting and confusing problem...what should one do with the case where Q_n = 0 and Q_(n+1) = (not used), and Q_n = 1 and Q_(n+1) = (not used)? Suppose your equations were J = S and K = R and you treated the invalid case as a Don't Care. Then in the case where S = 1 and R = 1, J and K will be 1, and the output Q will be the race condition or toggle, since the flip flop being used is JK. However, if you use the equations J = S*/R and K = /S*R, then when S = R = 1, J and K will be zero. Then, the output of the flip flop will be equal the previous state (memory). In other words...regardless of your logic equations for S and R, there is no way to have an invalid case. Or is there?

[@Hurricoaster]

By the way...I'm struggling to understand how it would make sense to even consider representing an SR flip flop using a JK flip flop. Wasn't the purpose of the JK flip flop to make use of the invalid case of the SR flip flop? Wouldn't it be...counter-intuitive and unnecessary to go the other way?

[@Hurricoaster]

As for the SR FF represented using a T FF, my equation was T = /Q*S*/R + Q*/S*R. I am assuming that the invalid cases should never be allowed to happen, and this SOP guarantees it.

[@Hurricoaster]

If you allow for the invalid cases, the equation would be T = /Q*S or Q*R, but this would result in a toggle, which isn't exactly how an SR flip flop operates
