What is IMD (Intermodulation Distortion)?

When at least two signals are utilized in a nonlinear framework then Intermodulation Distortion (IMD) occurs. Intermodulation distortion (IMD) is the amplitude modulation of signals containing at least two distinct frequencies, brought about by nonlinearities or time difference in a framework. Intermodulation is brought about by non-linear conduct of the signal processing (physical equipment or even algorithms) being utilized. Intermodulation is additionally typically undesirable in radio, as it makes undesirable spurious emissions.
