—A mathematical framework, based on state-space modeling, for the description of limit cycles (LCs) of 1-bit sigma–delta modulators (SDMs) is presented. It is proved that periodicity in bit output pattern of the SDM implies a periodic orbit in state-space variables. While the state-space description is generally applicable for periodic inputs, the focus is(More)
The paper introduces the coding technique that is used by the Super Audio CD system for lossless compression of 64 times oversampled one-bit audio data. The technique has been coined "DST" (direct stream transfer). The individual steps in the encoding and decoding process are detailed. The performance of the lossless compression algorithm, as a function of(More)
