6. Quantizing, Approximation Errors and Sample Size. Samples, the periodic snapshots of the instantaneous amplitude of an input signal taken by the ADC, are assigned numeric values that the computer or digital circuit can use in a process called quantization.The number of available values which can be assigned is determined by the number of bits (0's and 1's) used for each …

For speech, we could modify quantization steps as we go, by estimating the mean and variance of a patch of signal values and shifting quantization steps accordingly, for every block of signal values. That is, starting at time i we could take a block of N values fn and try to minimize the quantization error:

Chapter 2 Quantization. Basic operations for AD conversion of a continuous-time signal x(t) are the sampling and quantization of x(n) yielding the quantized sequence x Q (n) (see Fig. 2.1).Before discussing AD/DA conversion techniques and the choice of the sampling frequency f S = 1/T S in Chapter 3 we will introduce the quantization of the samples x(n) with finite number …

1. Quantization and sampling. ¶. Most signals in life are continuous: pressure waves propogating through air, chemical reactions, body movement. For computers to process these continuous signals, however, they must be converted to digital representations via a Analog-to-Digital Converter (ADC). A digital signal is different from its continous ...

A digital signal is a sequence of discrete symbols. If these symbols are zeros and ones, we call them bits. As such, a digital signal is neither continuous in time nor continuous in its range of values. and, therefore, cannot perfectly represent arbitrary analog signals. On the other hand, digital signals are resilient against noise.

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).
