For the past several years, researchers have been creating living logic gates, using the genetic on and off switches we’ve discovered in the biochemical world to create simple logical functions. But ...

It’s possible to use an 8:1 multiplexer to implement any 3-input logical function, but can we use it to implement a 4-input function? On the one hand, some logic problems never seem to go away. On the ...

Toshiba Corporation has launched a new series of CMOS multi-function gate logic devices that support 5V systems and that are housed in small packages suitable for mobile devices such as mobile phones, ...

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 ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

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 ...
