The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

As variable frequency drives (VFDs) are becoming the primary go-to solution for motor control, their capability is not something that can be matched. With every new generation comes better performance ...

Kitty is one of the many terminal emulators for Linux and macOS. You probably don’t think much about your terminal emulator: it gets out of the way, letting you type on the command line and work with ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
