Abstract
This entry gives a brief overview of the recent developments in audio sound reproduction via modern sampled-data control theory. We first review basics in the current sound processing technology and then proceed to the new idea derived from sampled-data control theory, which is different from the conventional Shannon paradigm based on the perfect band-limiting hypothesis. The hybrid nature of sampled-data systems provides an optimal platform for dealing with signal processing where the ultimate objective is to reconstruct the original analog signal one started with. After discussing some fundamental problems in the Shannon paradigm, we give our basic problem formulation that can be solved using modern sampled-data control theory. Examples are given to illustrate the results.
