Long before tubes and semiconductors became the main active components in digital circuitry, relays were used for highly sophisticated control of electronic systems. Today’s retro-engineering and ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

If you’re at all familiar with digital computing, you’ll know that computers represent everything in binary values of one and zero. Except that’s not technically the only way to do computing! You can ...
