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 ...

If the planet Vulcan had microbes, they might look something like this. Scientists have engineered bacteria that can perform four basic operations of logic: AND, OR, NAND and NOR. By combining these ...

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 ...
