Quantization noise is typically caused by small differences (mainly rounding errors) between the actual analog input voltage of the audio being sampled and the specific bit resolution of the analog-to-digital converter being used. This noise is nonlinear and signal dependent. Chapter 5 Sampling and Quantization Often the domain and the range of an original signal x(t) are modeled as contin- uous. That is, the time (or spatial) coordinate t is allowed to take on arbitrary real values (perhaps over some interval) and the value x(t) of the signal itself is allowed to take on arbitrary real values (again perhaps within some interval).
An authoritative analysis of quantization (roundoff error), ideal for those working in digital signal processing, control or numerical analysis. The book includes uniform, and floating-point, quantization. Written by expert authors, including the founder of the field and formulator of quantization noise theory, Bernard Widrow.5/5(1). CHAPTER 14 REVIEW OF QUANTIZATION Nonlinear tone-transfer curve of quantizer, showing a linear region. Quantization Quantization converts continuously valued measured irradiance at a sample to a mem-ber of a discrete set of gray levels or digital counts, e.g.,the sample f[x,y] e.g., f[0,0] = W.
Book Description This book is intended to fill the gap between the "ideal precision" digital signal processing (DSP) that is widely taught, and the limited precision implementation skills that are commonly required in fixed-point processors and field programmable gate arrays (FPGAs). I'm studying the quantization of an audio signal and in particular the SQNR (Signal to Quantization Noise Ratio). The book on which the study says that: where: N is the number of bits in the digital representation; V indicates that the signal voltage varies between -V and +V. I don't understand how these calculations were carried out.

The book includes uniform, and floating-point, quantization.

Quantization of two or more variables - statistical analysis of quantization noise; Quantization of two or more variables - general statistical relations between the quantization noises, and the quantizer inputs and outputs; Brand: Bernard Widrow.
The book summarizes the statistical theory of quantization. The properties and application conditions of the noise model of quantization are discussed in details. Limits of applicatibility are formulated. The theory is developed for uniform quantizers, then it is extended to floating-point number representation.
Applications to roundoff in FIR/IIR filters, in feedback control systems, and in numerical calculations. Quantization Noise: Roundoff Error in Digital Computation, Signal Processing, Control, and Communications Written for statisticians, physicists, and engineers in the field of digital signal processing and Quantization Noise book, this book provides an authoritative analysis of quantization noise.
"Quantization or round-off is a nonlinear operation that is effected whenever a physical quantity is represented numerically," stated Widrow inin a seminal doctoral thesis and published paper that is reprinted as Appendix M in this unique, authoritative, and most advanced book on round-off error.
The granularity of such signals, caused by both sampling and quantization, can be analyzed by making use of sampling theory. This chapter reviews sampling theory and develops it in a conventional way for the analysis of sampling in time and for the description of sampled signals.
the quantization noise is a time series represented by ν 1, ν 2, ν 3, Suppose that the input time series is stationary and that its statistics satisfy the conditions for multi- variable QT II (it would be sufﬁcient that two-variable QT II conditions were satisﬁedFile Size: KB.
Quantization Noise Quantization is the mapping of a range of analog voltage to a single value. Staircase curve of a linear N Bit ADC Converter • Assume that the input in “busy”, moderate signal level. • Green curve is a scaled version of Vin without any quantization. • Red curve is the ADC Size: 98KB.
Quantization noise can be reduced by the use of nonuniform spacing of levels, to provide smaller steps for weaker signals and coarser quantization near the peak of large signals. Quantization noise can be minimized by an optimum level distribution that is a function of the probability density of the signal.
Quantization noise results when a continuous random variable is converted to a discrete one or when a discrete random variable is converted to one with fewer levels. In images, quantization noise often occurs in the acquisition process.
This is the only book I know of with a rigorous analysis of Quantization Noise. I had previously done some work on the “Spectrum of Quantization Noise and Conditions of Whiteness”; so I was interested in what this book presented.
It would have been good if it had more on “Saturation Effects”; which was limited to two pages in an appendix.5/5(1). Quantization Noise: Roundoff Error in Digital Computation, Signal Processing, Control, and Communications by Bernard Widrow.
If you are working in digital signal processing, control or numerical analysis, you will find this authoritative analysis of quantization noise (roundoff error) invaluable. An important feature of this analysis is that the quantization error appears very much like random noise.
This sets the stage for an important model of quantization error. In most cases, quantization results in nothing more than the addition of a specific amount of random noise to the signal.
The book contains a very thorough mathematical analysis and presentation on the subject of quantization noise. It is the only such book I have found, apparently not many authors dare to dive into this field.
It is a nice exception to the many sloppy works. A Novel Time-Domain Phase Quantization Noise Extraction for a VCO-based Quantizer Abstract: A highly linear SAR-VCO MASH delta-sigma ADC architecture is presented. OTA based analog integrators are not needed whereby the ADC is mostly digital and process scaling friendly.
