A programmable logic controller (PLC) is actually an “industrial computer” that can work stably in complex environments. It can process switching signals, digital signals, analog signals, etc. from ...

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 University of Tokyo, succeeded in the development of a novel transistor, the “atom transistor,” which performs both logic and memory functions while reducing power consumption by one million times ...

If you've encountered the word "Boolean" but aren't quite sure what it means, this is the guide for you! From definitions of key terms to easy-to-follow examples, here's everything you need to know ...

While function generators or analog signal generators are ubiquitous in their utility, we haven’t seen much of logic function generators on Hack a Day. Luckily, [Dilshan] sent in a really neat ...
