Deterministic analysis of sigma–delta modulation for linear and non‐linear signal reconstruction

Abstract

Deterministic analysis is becoming increasingly popular to study the theoretical mechanisms of modulation, as opposed to the classical noise-shaping approach. This paper gives an overview of its application to the speciÿc problem of signal reconstruction. Once an input signal has been processed through a modulator of given speciÿcations, the fundamental question is to know what deterministic information can be retrieved about this signal from the output.
