IMD2 (IMD3)
From a dual tone input sinusoid (f
t1
and f
t2
, these frequencies being chosen according to
the coherence criterion), the intermodulation distortion products IMD2 and IMD3
(respectively, 2nd and 3rd order components) are defined, as follows.
The ratio of the RMS value of either tone to the RMS value of the worst second (third)
order intermodulation product.
The total InterModulation Distortion (IMD) is given by:
where:
with
corresponding to the power in the intermodulation component at frequency f
t
.
