A specialized segment of the electrical construction and maintenance industry, AC motor control is an area that requires specific knowledge in order to troubleshoot motors effectively and ensure ...

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 ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

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 ...

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 ...
