Excel's logical functions test whether a statement or data is true or false, before enabling the program to carry out an action based on the result. They are useful for analyzing data, automating ...

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 ...

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 ...

Imagine this: you’re managing a sprawling Excel spreadsheet with thousands of rows of data. You need to identify high-priority tasks, flag anomalies, or categorize entries based on specific rules.

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 ...

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 ...

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 ...

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 ...
