    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.

    Care to post a schematic? We can talk then with something at hand, not just in theory and abstract guidelines.
