A theory of overall quantization noise for nonsubtractive dither was originally developed in unpublished work by J.N. Wright and by T.J. Stockham and subsequently expanded by L.K. Brinton, S.P. Lipshitz, J. Vanderkooy, and R.A. Wannamaker. It is suggested that since these latter results are not as well known as the original results, misunderstanding ...

Summary: In this article we propose a general definition for the quantization of classical mechanics with an arbitrary phase space. We consider the case where the phase space is a complex Kählerian manifold. As an example we consider uniform bounded regions in \(\mathbb C^n\) with a Bergman metric, and also the two-dimensional cylinder and torus.

A simple upper bound is derived to the difference in performance obtained from applying a given quantizer to two different sources. This provides a bound on the performance loss or mismatch resulting when applying a quantizer designed for one source to another.

The efforts of most theoretical physicists of this century have been directed towards that branch of the physical science which is commonly called “Quantum Theory.” Physically, Quantum Theory was postulated because of a vast amount of physical evidence which led to the postulates ...

Quantization improvement in MRI using dual quantizers
IEEE Transactions on Medical Imaging, 1991The quantization of magnetic resonance imaging (MRI) data can cause information loss due to quantizer/data mismatch. The authors address a method for improved quantization as well as techniques for measuring the improvement in such methods. A dual quantizer scheme is described and simulated which is fast and more accurately quantizes MRI data than ...

Charge quantization and canonical quantization
Journal of Mathematical Physics, 1976Dirac’s charge quantization condition is derived by means of a canonical quantization procedure of an enlarged classical phase space in which the interaction constant is a dynamical variable. The charge quantization condition follows by imposing a superselection rule. The method avoids string singularities and does not depend on spherical symmetry. The

Quantization of Waves (Second Quantization)
1984In the introduction to elementary quantum mechanics, much of the experimental evidence presented concerns the quantum (or particle) nature of light (Compton effect, photoelectric effect, infrared catastrophe, etc.), yet the wave nature of particles and the Schrodinger equation dominates most considerations from then on.
