HiFiBerry USB – distortion measurements

Distortion measurements

The following chart show the harmonic distortions for both input and output together. The input and output of the circuit were connected by a loopback cable.


Overall, the distortions are at about 0.005% over the full frequency range.

We also did some measurements, what would happen with the cheap version of this card – without the additional REG103 voltage regulator. You can see the results here.
