Abstract
In order to monitor the transmission quality of digitized signals, the quantization interference power is measured in a region where no useful signal is being transmitted. The quantization step for an associated D/A converter can be determined from the quantization interference power, and an assessment can be made, based on a comparison, as to whether the D/A converter is meeting the required quality parameters.
