    I have a bit knowledge on how j-k flip flop works and were currently discussing it on my school but I still dont get this one.
    how does the counting goes back to zero"0" when it hits to "9"?
    can some help me explain this one. ( :

    Make a truth table. Look at what state the flip flops are in with a count of 9. Then what happens with the next clock?

    we are doing this as well, I can follow through how the last flip-flop is going to be reset, but the others. Any help please? I understand that with B and C both low going through an AND gate J is forced low and last flip flop is reset, how are the first three reset?
