Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively. There are only two ...

There are two main reasons mathematics has fascinated humanity for two thousand years. First, math gives us the tools we need to understand the universe and build things. Second, the study of ...
