Homework Help: Logic diagram ,,help

  1. Oct 2, 2007 #1
    hi ^^

    Draw the logic diagram of the following expression. The diagram should correspond directly to the equation. Assume that the complements of the inputs are not available:
    a . XYZ + X’Y’ + X’Z’.
    b . B(A’C’+AC) + D’(A+B’C)

    what does it mean ?
    do i have to draw the inverter? or not?
    should i use the sum of products form?

    In item a you don't need to use inverters. Use De Morgan's law and implement X'Y' and X'Z' using nor gates instead of nand gates.
    In item b you should use inverters.
