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 ...

A network of sensors has begun providing what may be the first collection of utility customer readings of one critical measure of power quality reaching U.S. homes. Some 1-million plug-in devices ...

Researchers in Malaysia have published a study of total harmonic distortion (THD) reduction techniques in PV systems and claim to have found an holistic and systematic approach. The paper Advances in ...

As discussed in Chap. 5, harmonic currents produced by nonlinear loads can interact adversely with the utility supply system. The interaction often gives rise to voltage and current 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 ...

Harmonic distortion arises when electrical waveforms deviate from their ideal sinusoidal shape, a phenomenon commonly introduced by non-linear devices such as power electronic converters, ...

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, ...

Many continuous-conduction-mode PFC controllers use a nonisolated boost topology with average current-mode control. Examples of such controllers are the UC1852, UC1854/UC1854A/UC1854B family and the ...

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 ...

Tektronix must have been quite a place to work back in the 1980s. The company offered a bewildering selection of test equipment, and while the digital age was creeping in, much of their gear was still ...
