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:
Ok so in my book I've found a similar circuit, except it's to count through the sequence 1 2 3 4 and so on. And I'm not sure at all how I'd go about changing the circuit to work for the question above. The circuit I have is:
Any ideas?
