In logarithmic quantization, one does not quantize the incoming signal but log of it to maintain signal to noise ratio over dynamic range. Dr Inayatullah Khan
No. of quantization levels = 2^10 = 1024Voltage range = 10VQuantization interval = 10/1024 = 9.77 mV / level.
—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.

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.
Higher quantization levels, such as 16-bit or 24-bit, allow for more faithful reproduction of a signal, as they provide a greater number of discrete amplitude levels. This improves the resolution of the audio or signal, reducing quantization noise and capturing more detail in the original waveform. Consequently, using a higher quantization level enhances dynamic range and overall sound quality.

The ideal Quantization error is 2^N/Analog Voltage
Sampling Discritizes in time Quantization discritizes in amplitude
There are two types of quantization .They are, 1. Truncation. 2.Round off.
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.
Quantization refers to the process of approximating continuous values with discrete values. In physics, it often pertains to the quantization of physical quantities like energy or charge into discrete levels. In digital signal processing, quantization refers to converting analog signals into digital format by rounding or approximating data values to a set number of bits.
Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion(ADC) in telecommunication systems and signal processing.
