Drawing a circuit diagram for a Boolean expression

  1. Oct 8, 2013 #1
    1. The problem statement, all variables and given/known data

    Draw the logic diagram for the following Boolean expression. The diagram
    should correspond exactly to the equation. Assume the complements of the inputs are
    not available.

    B(A'C'+AC) + D'(A+B'C)

    2. Relevant equations

    3. The attempt at a solution

    I can't find any way to simplify the expression in order to remove the complements.

    So, I tried to look for other ways to solve the problem. I'm wondering if I could use a NAND gate or a NOR gate since these are considered to be universal gates and can represent an inverter.

    yes, or you just USE an inverter where needed. I don't see anything that says you can't, it just says they are not directly available at the input, not that you can't create them.
