Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD ... If a circuit produced a perfect sine wave, there would be no harmonics.

and we’re guessing that many of you will be familiar with the mathematical derivation of a square wave from a series of harmonic sine waves. Distortion in an audio device is measured by looking ...

A good assumption for most utilities in the United States is that the sine-wave ... most distortion is periodic, or an integer multiple of the power system fundamental frequency. That is, the current ...

Harmonic distortion is often measured with a single tone test signal, that is, a sine wave at a particular frequency (specified in the data sheet). To save test time, distortion can be measured in ...

The recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy,” discloses a low THD sine generator which led me to dust off a design that ... This is also a good time to mention that ...
