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 ...

Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...
