Moment preserving quantization (signal processing)

IEEE Transactions on Communications, 1991
The general solution to the moment-preserving (MP) quantizer problem is presented. It is shown that the moment preserving quantizer is related to the Gauss-Jacobi mechanical quadrature, the output levels of the N-level MP quantizer are the N zeros of an Nth degree orthogonal polynomial associated with the input probability distribution function, and ...

Signal-dependent variable-resolution quantization for continuous-time digital signal processing

2009 IEEE International Symposium on Circuits and Systems, 2009
A variable-bit quantization scheme is proposed for use in the context of continuous-time digital signal processing, with resolution depended on signal speed. It is shown that a decrease in resolution for fast inputs does not corrupt the inband spectrum, while leading to power savings. Analysis and extensive simulations are provided.

Vector-based signal processing and quantization for image and video compression

Proceedings of the IEEE, 1995
Image and video compression has become an increasingly important and active area. Many techniques have been developed in this area. Any compression technique can be modeled as a three-stage process. The first stage can be generally called a signal processing stage where an image or video signal is converted into a different domain. Usually, there is no

Digital signal processing in continuous time: a possibility for avoiding aliasing and reducing quantization error

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
The operation of digital signal processors in continuous time is discussed. It is shown that the main advantages of digital arithmetic can be maintained in such operations, while aliasing of the signal and the quantization error is avoided altogether. Continuous-time operation makes possible a smaller number of bits for a given signal-to-quantization ...
