Hi,

How do I design the synchronous number that periodically counts (0-6-4-2) with JK FF using?

How many different states do you have?

How many FF do you need to encode those states?

You need to show YOUR best attempt to solve the problem, not just ask others how to do it.

Note that there is trick in this assignment.

Why are all the J & K inputs unconnected?
Why do you need 4 FF's to show 4 different values?
How do you make a JK FF always contain a 0?

That should get you started

are four states in total, not 2.

How many states does one flip-flip have?

If I have an 8-bit register, how many unique 8-bit patterns can I show?

Yes one flip-flop of 2 bit 4 state

8-bit pattern of N bits 2^N formule. Am i wrong?

Let us try a different approach.

I have a coin. I flip it into the air once and it lands on the floor.
How many different ways can it land on the floor?
