    Write out the truth table for a full adder.

    Inputs: a, b, and cin.
    Outputs: cout and S.

    Simplify the functions by means of karnaugh maps and implement using the MUX's.

    No problem.

    Georacer is right, though.

    Please put more effort into making a half decent attempt towards solving the problem before posting for help.

    Please don't use PMs to try to get answers. You also can't receive PMs (it is not set up for it), which means this was the only way to answer you. My signature says it all.

    I don't mind special requests for public posts. This was posted about 45 minutes after the email, and it looks like you have it well in hand.
