Intermodulation Distortion

Technology / Home Audio / Intermodulation Distortion: A species of Distortion that results when one set of frequencies is superimposed on, or is modified by, another to produce a third frequency not present in the original signal. Quantifies the distortion products of nonlinearities in the unit under test that causes complex waves to produce beat frequencies, i.e., sum and difference products not harmonically related to the fundamentals.

Distortion

Technology / Home Audio / Distortion: Any departure from a true and accurate reproduction of the original waveform. It can include Noise, Clipping Distortion, Harmonic, and Intermodulation Distortion. These last two forms are fairly commo MORE

Total Harmonic Distortion (THD)

Technology / Home Audio / Total Harmonic Distortion (THD): Total harmonic distortion is a measure of the how much a given audio device may distort a signal through the introduction of added harmonics or overtones. These figures are usually given as percentage MORE
