First measurements of our HiFiBerry DSP Light

Today we had a look at the noise and distortions of the HiFiBerry DSP light. They look promising. Noise is not a problem at all – which is not the case for every DSP that is available on the market. The distortion figures are a bit above the typical distortions from the datasheet, but still at an acceptable level below 0.01%. The low noise figures show, that the PCB design works well with its clear separation of the analog and the digital part of the circuit.
