The main objective of this paper is controlling the mean-square reconstruction error induced by applying randomly dithered quantization, a stochastic round-off prescription, to the frame coefficients of a vector in a finite-dimensional Hilbert space.

This paper presents a model of sound propagation in a duct, for the purpose of active noise control. A physical model generally different from those explored in much of the literature is derived, with non-constant acoustic load impedance at the one e

A detailed mathematical investigation of multibit quantizing systems using nonsubtractive dither is presented. It is shown that by the use of dither having a suitably chosen probability density function, moments of the total error can be made indepen

This paper investigates the performance of randomly dithered first and higher-order sigma-delta quantization applied to the frame coefficients of a vector in a infinite-dimensional Hilbert space. We compute the mean square error resulting from linear

It is shown that quantizing systems without feedback respond to the use of particular spectrally-shaped dither signals quite differently from those with feedback paths. For each type of system, conditions are given which ensure that the quantization

A direct correspondence is demonstrated between the phenomenon of "stochastic resonance" in static nonlinear systems and the dithering effect well known in the theory of digital waveform coding. It is argued that many static systems displaying stocha
