Just because harmonics is becoming a more prevalent problem, that doesn't mean the subject is getting any easier to understand Harmonics are AC voltages and currents with frequencies that are integer ...

Comb-based optical frequency metrology and atom clocks have pushed the measurement of time and frequency to unprecedented precision in recent decades 1. The recently emerged miniature ...

Mixed-signal printed circuit boards (PCBs) present unique challenges in high-performance applications, such as vibration analysis and other multi-channel data acquisition systems. Nonlinear ...

Musical instruments and throats create different notes by making the air around them vibrate at particular frequencies (check out part one to find out how they do it). When you pluck the A string on a ...

When designing with interconnects, we're often concerned about issues such as crosstalk and reflections. We frequently ask for models from the manufacturers so we can run simulations to determine the ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

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 ...

Abstract: Wave motion lies at the heart of many disciplines in the physical sciences and engineering. For example, problems and applications involving light, sound, heat, or fluid flow are all likely ...

John Smith, a physicist at the University of New South Wales in Sydney, Australia, belts out an answer to this query. In both speech and singing, we produce sustained vowel sounds by using vibrations ...
