At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

Introduction – Because of their typically fast edge rates, crystal oscillators can generate a large number of high-order harmonics. Figure 1 indicates a generalized trapezoidal digital signal. The ...

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 ...

Industrial and commercial customers constantly scrutinize their monthly electrical usage, looking for ways to save money. Installing power factor correction capacitors can reduce costly penalties ...

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 ...

How to measure harmonics in a power system. Methodologies for reducing power system harmonics. A look at "triplen" harmonics. The IEEE standard 3002.8-2018, “Recommended Practice for Conducting ...
