    A Universal Serial Bus (USB) communication link requires acircuit that produces the sequence 00000001. You are to design asynchronous sequential circuit that starts producing this sequencefor input E=1. Once the sequence starts, it completes.If E=1, during the last output in the sequence, the sequencerepeats. Otherwise, if E=0, the output remains constan at1.
    a. Draw the Moore state diagram for thecircuit.
    b. Find the state table and make a state assignment.

    If someone could help me with part A, I am sure that I would be good from there. I have tried drawing the moore diagram out with nine states (one for the first input and then 8 for the sequence) but am stuck while trying to derive the equations needed for implementation.

    I am really stuck. I'd appreciate as much help as you can give but please post even if you only have time to point me in the right direction. Thanks!!

    Try to post the state diagram. If you manage that I guarantee that everything else will be easy for the mind (I don't promise anything for your hand though).

    Don't hog other people's posts. It is usportsmanship behaviour.

    Hello,

    I moved the post from Ranjita ningthoujam to its own thread.
