Homework Help: Boolean Algebra simplification question

  1. Sep 19, 2012 #1
    1. The problem statement, all variables and given/known data

    Lets say I have 4 inputs x1 x0 y1 y0

    if I have a sum-of-products say: x1x0'y1y0'+x0y1'y0

    can I simplify it to x0y1'y0 by pulling out x0y1'y0 giving x0y1'y0(y0'+1) knowing that 1+y0 is 1 and 1*signalz is signalz.

    Am I right in thinking this, I really dont want to do the truth table for this bad boy

    Sorry, not right. As a check, whenever you factor, remultiply to see if the result matches original.
