Op amps excel at providing many useful and clever solutions to routine or complicated circuit functions. A summing circuit is a perfect example. A summing circuit is typically used in applications ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

This file type includes high resolution graphics and schematics when applicable. A piezoelectric motor is a linear motor with bidirectional motion. It uses friction to grip the armature while a ...
