Figure 6. THD+N vs Voltage (Analog Input)
The THD+N from 10 mV
rms
to approximately 0.5 V
rms
is dominated by noise.
Figure 7. THD+N vs Voltage (Analog Input) Linear Scale
Here the THD+N versus output voltage is shown with linear scale. This makes it easier to see where
clipping occurs. Clipping is often defines as THD+N=1%.
