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 ...

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 ...

Now, the thing to remember is that we are using a CD4512 chip, whose truth table is shown below. The important thing to note here is that, in addition to the three multiplexer select controls, A, B, ...

The NOT function in Microsoft Excel is a built-in Logical function that reverses the logic of its argument. It ensures that one value is not equal to another. When given TRUE, NOT returns FALSE. When ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

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 ...

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 ...

A (long) while ago I presented you the Easy-phi project, which aims at building a simple, cheap but intelligent rack-based open hardware/software platform for hobbyists. With this project, you simply ...
