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 ...

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 ...

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 ...

Optical frequency combs are widely-used, high-precision tools for measuring and detecting different frequencies—a.k.a. colors—of light. Unlike conventional lasers, which emit a single frequency, these ...
