e/IMD3

Information
has gloss	eng: IMD3 refers to the intermodulation distortion from the third harmonic of a circuit. It is of particular importance in narrow band signals because its distortion is often in the signal band. This can be seen by looking at a signal that is made up of two sine waves, one at f_1 and one at f_2. When you cube the sum of these sine waves you will get sine waves at various frequencies including 2\times f_2-f_1 and 2\times f_1-f_2. If f_1 and f_2 are large but very close together then 2\times f_2-f_1 and 2\times f_1-f_2 will be very close to f_1 and f_2.
