The value of k is usually 6 (THD is calculated based on the first 5 harmonics).
12.2.4
Signal-to-Noise ratio (S/N)
S/N is the ratio of the output signal power to the noise power, excluding the harmonics and
the DC component:
(8)
12.2.5
Spurious Free Dynamic Range (SFDR)
The SFDR value specifies the available signal range as the spectral distance between the
amplitude of the fundamental (a
1
) and the amplitude of the largest spurious harmonic and
non-harmonic (max (s)), excluding the DC component:
(9)
12.2.6
InterModulation Distortion (IMD)
The second-order and third-order intermodulation distortion products IMD2 and IMD3 are
defined using a dual tone input sinusoid, where f
1
and f
2
are chosen according to the
coherence criterion.
IMD is the ratio of the RMS value of either tone to the RMS value of the worst, second or
third-order intermodulation products.
