Intermodulation Calculator Help


Intermodulation (a.k.a. intermod) is the unintentional mixing of frequencies in a nonlinear device, such as an amplifier or mixer. Intermod products (resultant frequencies) are calculated by adding and subtracting the input frequencies and their harmonics.

Here's a Wikipedia article.

This calculator computes intermod for RF signals. It could be used for audio signals as well, but the expression of frequencies in MHz isn't helpful in that case.
