Ok I'm afraid I'm going to need to ask for more help on this question! I failed my exam and I have to do a repeat exam, and it's tomorrow hah. And this question came up on the original exam!
I've been trying to figure out how to do it. I found a way, but it involves having about three logic...
Exam question:
Use J-K flip-flops to design the logic for a synchronous up/down counter that counts "up" through the sequence 1 2 6 3 5 7 f the input switch UP is 1, and "down" through the sequence 7 2 1 5 3 6 if UP is 0. Verify that the counter is self-starting.
What I know so far...
