TAS5028 Audio Processing
The TAS5028 digital audio processing is designed such that noise produced by filter operations is maintained
below the smallest signal amplitude of interest, as shown in Figure 1 - 13. The TAS5028 achieves this by
increasing the precision of the signal representation substantially above the number of bits that are absolutely
necessary to represent the input signal.
