AB  - Because conventional sigma–delta modulators have a proclivity toward instability when excited by high-amplitude audio signals, a modified detection process incorporates an energy metric. This new paradigm uses the sums of the energy in the filter integrators as part of the five-sample look-ahead. Unlike a conventional sigma–delta modulator, which only considers the filter output, this approach also lowers the stored energy within the filter. As an intrinsic tradeoff, increased stability at high levels increases noise modulation. An energy-balance algorithm can use a highly parallel matrix operation for computational efficiency.
