The terms positive logic and negative logic refer to two conventions that dictate the relationship between logical values and the physical voltages used to represent them. Although the core concepts ...

Although wrapping one’s brain around the concepts of positive, negative, and assertion-level logic can require some mental gymnastics, understanding these topics can be very rewarding. Although ...

Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

Studia Logica: An International Journal for Symbolic Logic, Vol. 109, No. 4 (August 2021), pp. 829-857 (29 pages) Positive monotone modal logic is the negation- and implication-free fragment of ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...
