Device Support (continued)

Total Harmonic Distortion (THD) THD is the ratio of the power of the fundamental (PS) to the power of the first

five harmonics (PD).

(10)

THD is typically given in units of dBc (dB to carrier).

Two-Tone Intermodulation Distortion (IMD3) IMD3 is the ratio of the power of the fundamental (at

frequencies f1, f2) to the power of the worst spectral component at either frequency 2f1 – f2 or 2f2 –

f1). IMD3 is given in units of either dBc (dB to carrier) when the absolute power of the fundamental

is used as the reference, or dBFS (dB to full scale) when the power of the fundamental is

extrapolated to the converter’s full-scale range.
