## Coursera Unit 1.1: Boolean Function and Outcome 1

 In the truth table for a Boolean function, is there a reason why we should only select the rows that result in the outcome of 1?

 Administrator Since I don't have access to the Coursera course, I'm not quite sure what you are referring to without more info, so I'm inferring quite a bit here. When implementing a logic function, a very common way of doing it is as an OR of all of the combinations of inputs that result in the function being TRUE (i.e., a 1). When doing this, we take each row of the truth table for that function that produces a 1 and use and AND gate to produce a logic HI for that particular set of inputs. We then combine the outputs of all of these AND gates with an OR gate. Hope that helps.

 Thank you WBahn It helps and I know the process actually. But, my real question is, why do we use only the outcomes where the function is TRUE, why did we neglect the outcomes that result is FALSE? What is the reason?
