Pulse Width Modulation Tools

The Pulse Width Modulation (PWM) analysis feature is dedicated to the analysis of the sound emitted by certain electrical rotating machines. It allows you to study the various PWM tones of this kind of sound.

Sound: Analysis and Specification provides tools as follows:

  1. Select then modify some PWM orders in a time-frequency representation.

  2. Detect precisely the fundamental PWM frequency from the sound.

  3. Create a PWM profile (frequency evolution vs time along with a constant PWM frequency) to be associated to a signal.
