The requirements for high resolution audio circuits
are characterized by extremely high dynamic range and
relatively low signal frequencies. For
digital-to-analog and analog-to-digital converters
this implies special challenges related to the very
high resolution needed in the converter design. The
dominant design paradigm for audio converters is
delta-sigma modulation, a process in which speed is
traded for resolution through the means of
oversampling and noise-shaping.
Analysis of delta-sigma modulation is non-trivial and
publications are often highly theoretical, requiring
