CONCEPTS
. COMBINATION LOGIC GATtrS
In previous^ experiments^ you have^ learned^ that^ Logic^ Gates can^ be^ used^ to evaluaLe when all inputs are at logicat 1 (AND^ Gate), when^ ANY^ input is^ at logicat 1 (oR^ Gate) and that an input can be reversed^ between^ logical^1 and O (INVERTER Gate). When two or more logic gates^ are used in combination to evafuate various input conditions, the resulting^ circuit is called COMBINATION LOGIC.
