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 critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

The power quality industry has developed certain index values that help us assess the quality of service as it relates to distortion caused by the presence of harmonics. These values, or harmonic ...

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 ...

Measuring an op amp’s THD(total harmonic distortion) at frequenciesbelow 100 kHz is problematicbecause modern amplifiers have a THDrating that is much lower than that ofmost test equipment. The ...

Agilent Technologies has introduced a range of 30MHz waveform generators which are designed for very low jitter and low harmonic distortion. The total harmonic distortion is less than 0.04% and ...

We all know what distortion sounds like. We’ve heard it in heavy metal tunes, cheap iPod docks and the crummy speakers at Taco Bell drive-thrus. And we’ve all read distortion specs on things like ...
