Signal-to-Noise Ratio (SNR):
The ratio of the output signal power to the noise
power, excluding the harmonics and the DC component.

Spurious Free Dynamic Range (SFDR):
The number SFDR specifies available
signal range as the spectral distance between the amplitude of the fundamental and
the amplitude of the largest spurious (harmonic and non-harmonic, excluding DC
component.

Intermodulation distortion
Spectral analysis (dual-tone)
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.
IMD2 (IMD3):
The ratio of the RMS value of either tone to the RMS value of the worst
second (third) order intermodulation product.
