How are harmonics generated?

Harmonics are the result of nonlinear loads that convert AC line voltage to DC. Harmonics flow into the electrical system because of nonlinear electronic switching devices, such as variable frequency drives (VFDs), computer power supplies and energy-efficient lighting.

How do you add harmonics to a signal?

So yes, if you want to add odd harmonics, put your signal through an odd-symmetric transfer function like y = tanh(x) or y = x^3 . If you want to add only even harmonics, put your signal through a transfer function that's even symmetric plus an identity function, to keep the original fundamental.

Does clipping add harmonics?

In the frequency domain, clipping produces strong harmonics in the high-frequency range (as the clipped waveform comes closer to a squarewave). The extra high-frequency weighting of the signal could make tweeter damage more likely than if the signal was not clipped.

What is a harmonic process?

Harmonic motion refers to the motion an oscillating mass experiences when the restoring force is proportional to the ​displacement, but in opposite directions. Harmonic motion is periodic and can be represented by a sine wave with constant frequency and amplitude.
