In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

Based on a Microchip 12F675 MCU, this programmable window comparator lets users dynamically select the window characteristic and tolerance. It's aimed at voltage-monitoring applications. A voltage ...

A window comparator usually employs 2 comparators with one output indicating the input is somewhere between two limits. In these examples, a third comparator is added to display all three conditions ...

A continuity tester, as found on most multimeters today, is a great tool for finding broken connections and short circuits. But once you’ve found a short, it’s up to you to figure out which part of ...
