vvv A Unique Approach to Digital Gates. Initial Digital Gate Concepts. Most textbooks present the basic concepts of 0 and 1 inputs, using a Truth Table to indicate the output results. Forget the 0s and 1s approach for now, Because there really is A MUCH better way. vvv Consider nicknaming the Or Gate as the Any Gate: Now consider this simple fact about an OR Gate. No matter how many inputs there are, the gate will go active ANY time ANY one of the control inputs meet the right state or condition. You should be able to see why I suggest the nickname The ANY Gate , because of those multitude of input possibilities that can make that gate go active. Now, are you ready for this? If you look closely at what we have just said, and compare all of those possibilities of the OR Gate input controls, v.s. what it will take to make the OR Gate go active, you will see that it is a mirror image of the AND Gate. Think of it this way, even with the OR Gate, there is ONLY ONE TIME that the OR Gate will NOT go active. + !
