Question
I'm trying to get d flip flops to output a sequence in binary that i determine, in this case 59640 and then repeat. I've made the truth table and the karnaugh maps, however when i minimize the karnaugh maps and try to build the circuit it will not work correctly. I am almost positive my truth table and karnaugh maps are correct, but i'm guessing that my minimization of the karnaugh maps is not. if anyone could help with checking over my work and minimizing the karnaugh maps i would greatly appreciate it.
Truth table with next state table, using D flip flops so D=Q+, then Da=A+ for the kmap, etc.
Db
Dc
Dd
Explanation / Answer
I'm not sure how you came up with your K-maps, but they are not correct: For Da, box 0 should be 1 For Db, box 0 should be 1, also box 6 should be 1 For Dc, box 0 should be 0, also box 6 should be 0 For Dd, box 0 should be 1 With the correct values, I get the following equations: Da = B*D Db = C + A + A'B' Dc = A Dd = A'B' + BD
