    Think of the sequence: 0, 1, 2, 3 , 4. That is how a sequential counter might count. Or 2, 4, 6, 8. It will follow some predicable sequence.

    A non-sequential counter would produce random numbers, or at least a count that did not follow a pattern.

    kkk.......thanks a lot.......by the way i have to design a synchronous counter that counts in the following sequence 0,3,6,9,12,15,0.....can u help me out?
    ..........i started by considering the present and next states of the data and then i made a table with the excitation table of a t flip flop.......i know i have to use four flip flops and then get logic from k maps and then implement using gates but i need to be sure about my answer........m preparing for my semesters.......so do reply......

    It counts by 3's, which is sequential. Look at how the operation proceeds to figure out the logic.

    You have another thread open in Homework.
