3. A sequential circuit has two JK flip-flops, A and B; two inputs, x and y; and one output, z. The flip-flop input functions and the circuit output function are as follows: JA-(Ay)x+By KA=y! (x+A'B) JB-B'y+Ax' KB-A9B 2-B'x+Axy a) Obtain the state table b) Design the sequential circuit given above using EL flip-flops where the characteristic table of El flip-flop is as given below. (hint: AJB-(A+BY ) EL O(n+1) 0 0 0 0 O(n) 1 0 Q(n) 1 1 1 1
