Homework Help: Boolean Algebra Question (Digital Logic Circuits)

  1. Feb 22, 2014 #1
    1. The problem statement, all variables and given/known data

    3. The attempt at a solution
    Is my solution correct or can I simplify it even further?

    Is your final gate OR or NOR?

    Oh, that should be a NOR. Other than that mistake is all my work correct?

    I see you applied de morgan's theorem to the AB term in the beginning, why did you not opt to apply it on the NOR function?

    Oh right, when I did this I didn't know you could use DeMorgan's on three terms, I just found this out today. I will simplify it further now with this new knowledge.

    That should eliminate the need for so many calculations, although it is important to learn them as well.

    I am not certain but I think applying de morgan's theorem to the NOR function might get you to a final solution in three steps
