ARRL | Intermodulation |
Intermodulation is a source of interference that arises from the combination of two or more signals at different frequencies in some kind of non-linear system.

Electronic Design | Understanding Intermodulation Distortion Measurements |
Intermodulation distortion is an important metric of linearity for a wide range of RF and microwave components. Fundamentally, it describes the ratio (in dB) between the power of fundamental tones and third-order distortion products.

Wikipedia | Intermodulation |
Intermodulation is caused by non-linear behaviour of the signal processing (physical equipment or even algorithms) being used. Practically all audio equipment has some non-linearity, so it will exhibit some amount of IMD, which however may be low enough to be imperceptible by humans. (read more) |
