Remark: In the following equations, P
effects of random noise, non-linearities, sampling time errors, and ‘quantization noise’.
SIgnal-to-Noise And Distortion (SINAD)
The ratio of the output signal power to the noise plus distortion power for a given sample
rate and input frequency, excluding the DC component:
It is derived from SINAD and gives the theoretical resolution an ideal ADC would require
to obtain the same SINAD measured on the real ADC. A good approximation gives:
Total Harmonic Distortion (THD)
The ratio of the power of the harmonics to the power of the fundamental. For k
harmonics the THD is:
where:
The value of k is usually 6 (i.e. calculation of THD is done on the first 5 harmonics).
Signal-to-Noise ratio (S/N)
The ratio of the output signal power to the noise power, excluding the harmonics and the
DC component is:
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:
