via Steve Jurvetson – Stan Williams, HP guru, has figured out a way to implement all logic functions without negation. It is easy to implement all logic functions using only NAND or NOR gates, but not ...

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 ...
