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 species 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 (ft1 and ft2, these frequencies being chosen
according to the coherence criterion), the intermodulation distortion products IMD2
and IMD3 (respectively, 2nd and 3rd-order components) are dened, 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.
