13. Glossary
Spurious-Free Dynamic Range (SFDR): — The ratio between the RMS value of the
reconstructed output sine wave and the RMS value of the largest spurious observed
(harmonic and non-harmonic, excluding DC component) in the frequency domain.
Intermodulation Distortion (IMD): — From a dual-tone digital input sine wave (these
two frequencies being close together), the intermodulation distortion products IMD2 and
IMD3 (respectively, second and third-order components) are defined below.
IMD2 — The ratio of the RMS value of either tone to the RMS value of the worst second
order intermodulation product.
IMD3 — The ratio of the RMS value of either tone to the RMS value of the worst third
order intermodulation product.
Restricted Bandwidth Spurious Free Dynamic Range — The ratio of the RMS value of
the reconstructed output sine wave to the RMS value of the noise, including the
harmonics, in a given bandwidth centered around f
offset
