    1- Draw the schematic implements a 3-to-8 decoder using only 2-to-4 decoders and logic gates.

    2- Design a counter that counts up when a control input w=1 and stays the same when w=0.
    The upward sequence is 000, 001, 010, 011, 100, 101, 110, 111.

    - Fill in the excitation-table for the counter with JK lip-flops.


    Help Me :(

    We're not a homework service, you need to at least make an effort. Post what you've done so far.

    Yeah, these are the times you wish you paid attention in class..

    What do you know about the parts involved, and what has you stuck?
