The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

When it comes to logic we know its all supposed to make sense. However for some of us, casting your mind back to class on logic gates and understand it all just make nonsense. When it comes to logic, ...

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 ...
