<p>does anyone know the basic concepts of this? I know that you put ones in where the sum will equal 1, but are any zeros put into it…?</p>
<p>Yeah you can put both the zeros and ones in it, but which one you need depends on whether you are using Product of the Sums or Sum of the Products method for your analysis.</p>
<p>(I’m assuming you are talking about for circuit design. I’ve heard some things I’ve used such as the truth table are also used in some Philosophy classes. )</p>
<p>Yes, usually all the boxes that aren’t ones have zero values put in them, at least in CS/EE classes. In some cases we don’t care what gets put in a box, such as when we aren’t able to use that value for our circuit (for example, a value of 10 for a 0-9 digit display).</p>
<p>Well, in the book they show that the map has blank spaces. But I think those places are supposed to be filled with zeros. So do the blank spaces just represent zero.</p>
<p>That is the way I am taking it.</p>
<p>Yes they are zeros. The book probably just left them out to save ink/ the author was lazy/ emphasize the 1’s.</p>
<p>i’ve never seen it filled in with zeroes. that’s just the way they’re represented.</p>
<p>Well maybe different people put it in different ways. I was just wondering because I had a friend who filled the blanks with zeros and I would always leave them blank. </p>
<p>Thanks for the feedback, I really appreciate it!</p>
