Total harmonic distortion (THD), is a popular measure of nonlinearity of a device. Learn about the considerable flexibility in defining THD while providing a relatively simple way to orchestrate all ...

The author is technical publications manager and a senior technical writer at Audio Precision in Beaverton, Ore. When reduced to its basics, the process of audio test and measurement is concerned with ...

Arteche PQ, Inc. has introduced a complete range of active harmonic filters. This new filter product line achieves 5% total harmonic current distortion (THD) by monitoring the flow of harmonic ...

A couple weeks ago I built a simple 1KHz 6Vpp Sine Wave Generator from a handful of opamps and passives I had laying around. You can check out that project here. I thought it would be fun to quantify ...

In Audioholic’s subwoofer reviews, our measurements are an analysis of a subwoofer's ability to accurately reproduce the source content. This involves testing its behavior with respect to linear ...

Testing high-resolution data converters with commercially available test equipment always has presented a significant challenge. Until recently, manufacturers of such converters had to extend their ...

Understanding the causes, consequences, and mitigation strategies for harmonic distortion in today's increasingly complex ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

This article is part of a multi-part series on how to identify, monitor, diagnose, and deal with harmonics in electrical power systems. Last month’s column discussed how to take the data gathered when ...
