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 ...

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...

For the first time, researchers have performed logic operations with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods open up research possibilities ...

The optoelectronic logic element AND, OR and XOR is considered, the output signal of which can be inverted when the input control signal is applied, thereby converting the logic element into NAND, NOR ...

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 ...

You will all no doubt be familiar with the 74 series logic integrated circuits, they provide the glue logic for countless projects. If you look back through old listings of the series you’ll find ...

Fuzzy logic extends classical binary reasoning by allowing truth values to vary continuously between 0 and 1, thereby modelling uncertainty, imprecision and partial membership in complex systems.
