A couple weeks ago I built a simple 1KHz 6Vpp Sine Wave Generator from a handful of opamps and passives I had laying around. You can check out that project here. I thought it would be fun to quantify ...

Total harmonic distortion (THD), is a popular measure of nonlinearity of a device. Learn about the considerable flexibility in defining THD while providing a relatively simple way to orchestrate all ...

A data acquisition system (DAS) is the standard measurement and analysis instrument for industrial, medical, and telecom applications including medical imaging, audio and vibration analysis, and ...

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 ...

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 ...

Pioneer Electric&Research has introduced a hardened digital multimeter featuring total harmonic distortion measuring on AC voltages. The Model PDM-550 has been designed for flight-line maintenance ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...
