This 18-bit data isthen fed to the volume control. It then passes through the sigma-delta modulator to the analogdriver and analog Left and Right signals.The user may resample and record the data with the Resampler SampleRate Converter (Chapter7.11). Because there is no automatic low-pass filtering, it is the user’s responsibility to avoidaliasing distortion.The user may add a PCM sidestream with the Sidestream Sigma-Delta Modulator input (Chapter7.12). As is the case with the Resampler SampleRate Converter, hardware doesn’t offerlow-pass filtering, so sufficient aliasing image rejection is the responsibility of the user.Version: 1.02, 2012-12-05 9
