Harmonic distortion is nonlinear distortion characterized by the
appearance in the output of harmonics other than the fundamental
component when the input wave is sinusoidal.

What is the name of the distortion which does not appear at the
harmonic frequencies of the fundamental component but at some
other frequencies? This type of distortion is often introduced
by nonlinear filters.
