This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

Building logic gates out of silicon is old hat, as is building them from discrete transistors, 555 chips, LEGO, and even gears. [Yukio-Pegio Gunji] and [Yuta Nishiyama] from Kobe University, along ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make up ...

In previous installments, we examined the different types of logic gates in detail, exploring their theoretical and practical applications. In this next part, we will dive into the practice of ...

The gates could be useful in rovers sent to hostile environments such as Venus, as well as in low-power computers intended to survive nuclear or electromagnetic pulse blasts. Engineers and scientists ...
