but we can show how an XOR is created from our three basic boolean gates. We know we have two inputs again -- A and B -- and one output. Let's start with an OR gate, since the logic table looks ...

The switch diagrams help clarify ... represented by expressions, to their simplest or, in some cases, a form using specific logic gates. There are math identities and simplification rules that ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...
