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 ...

Let's assume that you need to simultaneously look at the inputs and outputs of a 16-bit counter to determine a timing error, but you have only a 2-channel scope – how do you look all of the required ...

The guys over at hackshed have been busy. [Carl] is making programmable logic design easy with an 8 part CPLD tutorial. (March 2018: Link dead. Try the Wayback Machine.) Programmable logic devices are ...

In the early days of digital design, all circuits were designed manually. You would draw K-map, optimize the logic and draw the schematics. If you remember, we all ...

Industrial automation technologies have made manufacturing processes increasingly more efficient. Programmable logic controllers (PLCs) are commonly used in industrial automation, and many of these ...
