Could someone can explain how to get those two questions ans

Could someone can explain how to get those two questions\' answers. I am so confused. Thank you !

Solution

in ans 7:

from from behaviour table, J,K,Q(Present state) are acting as input. the table is created using JK flip-flop chararterstic table which given as, where J=K=0 then Q+=Q, J=0and K=1 then Q+=0,J=1and K=0 then Q+=1,J=1and K=1 then Q+=Q\'. Using this the behaviour table is filled.

Now to fill the T colomn ,uisng transient table of T flipflop ,where, Q=0 and Q+=0 then T=0,

  Q=0 and Q+=1 then T=1

Q=1 and Q+=0 then T=1

Q=1 and Q+=1 then T=0

Now use J,K,Q as input of K map and T as output of K map and simplifi we get

T=KQ+JQ\'

fOR 8)

from from behaviour table,T,Q(Present state) are acting as input. the table is created using t flip-flop chararterstic table which given as, where T=0 then Q+=Q, T=1 then Q+=Q\' . Using this the behaviour table is filled for Q+

Now to fill the J an K colomn ,uisng transient table of JKflipflop ,where, Q=0 and Q+=0 then J=0,K=x,

  Q=0 and Q+=1 then J=1, K=x

Q=1 and Q+=0 then j=x,k=1

Q=1 and Q+=1 then J=x,k=0

Now useT,Q as input of K map andJ and K as output,its can derive from table,

\'J=T and K=T
