i was given this task:

create a synchronous counter that counts from 0 to 9 then back to 0.
i am suppose to use jk flipflop and gray code..

I've already the state table ( gray code, example : 0000 -> 0001 and the corresponding values for jk : for output 0 -> 0 , j= 0, k = X (dont care))

what is the next step? k-map ? but how?

plsss help!!

If you have setup your State Table, the rest is easy. All you need to do is extract the 8 input functions, through a K-Map and use them to connect the FFs.

Post your State Table, so that we can comment and talk over it.
