Some examples of quantization include the digital representation of sound waves in audio files, the conversion of continuous voltage levels into discrete digital values in analog-to-digital converters, and the discretization of pixel values in digital images.
Quantization range refers to the range of values that can be represented by a quantization process. In digital signal processing, quantization is the process of mapping input values to a discrete set of output values. The quantization range determines the precision and accuracy of the quantization process.
Mid riser quantization is a type of quantization scheme used in analog-to-digital conversion where the input signal range is divided into equal intervals, with the quantization levels located at the midpoints of these intervals. This approach helps reduce quantization error by evenly distributing the error across the positive and negative parts of the signal range.
If the sampling frequency doubles, then the quantization interval remains the same. However, with a higher sampling frequency, more quantization levels are available within each interval, resulting in a higher resolution and potentially improved signal quality.
Quantization of energy typically only becomes noticeable at very small scales, such as the atomic and subatomic level due to the principles of quantum mechanics. At larger scales, such as in everyday observations, the effects of quantization are averaged out over many particles and energies, making them appear continuous.
A quantization codebook is a set of codewords that are used in quantization, a process that involves mapping input values to a limited set of output values. The codebook contains the predefined values to which the input signal will be quantized to, based on minimizing the distortion between the original and quantized signals. It helps in representing continuous values by discrete values.

There are two types of quantization .They are, 1. Truncation. 2.Round off.

Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion(ADC) in telecommunication systems and signal processing.
quantisation noise decrease and quantization density remain same.
You get Jaggies
Vector quantization lowers the bit rate of the signal being quantized thus making it more bandwidth efficient than scalar quantization. But this however contributes to it's implementation complexity (computation and storage).

theory were all proved by taking longer and longer sequences of inputs. This indicates that a quantization strategy that works with sequences or blocks of output would provide some improvement in performance over scalar quantization. In other words, we wish to generate a representative
