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 ...

The study of harmonics is expansive. Although the theory has been well established, the effects on the electrical system are still being discovered. Lately, this has been the case with high order ...

Chirp signals are fast, accurate, and provide information that may be more difficult to obtain in other ways, as Mark A Martin, Jayant Datta and Xinhui Zhou explain. Figure 1: The frequencies of the ...

Up to now, this series has primarily discussed the DC specifications of an ADC. Now, we will talk about AC specifications like distortion and noise in the ADC. Total Harmonic Distortion (THD) is, as ...

Coming to grips with the semantics and vocabulary that apply to “distortion” takes a little discipline, but it isn’t all that intimidating. All you need is a little patience to go over the relevant ...
