This application note reviews a circuit technique that is used to create an analog signal output using Pulse Width Modulation (PWM). The paper explains the theory and provides some circuit examples.

Pulse width modulation (PWM) control, which uses variable-width digital pulses to represent the amplitude of an analog waveform, has been around for decades. The first specialized PWM IC dates back to ...

This file type includes high resolution graphics and schematics. You can build an analog calculator using a pulse-width modulator (PWM) to perform accurate four-quadrant multiplication and division.

The modules are intended for test engineers, technicians, and others working with high-speed machinery, equipment test beds, and other applications that monitor high-frequency analog signals and ...
