For perceptual audio coding, quantization involves representing the outputs of the filterbank by a finite number of levels with the aim of minimizing the subjective impairments of quantization noise. The characteristics of a quantizer can be specified by means of the step size and the range, as shown in Figure 4.7.While a uniform quantizer has the same step size throughout the input …

There are two types of quantization depending on the step size. They are uniform quantization and non-uniform quantization. The equation to find the step size (d) is given below. The Xmax is the maximum value of the signal and Xmin is the minimum value of the signal. The L is the number of levels that divide the signal. What is Uniform ...

Quantization can be classified as uniform quantization and nonuniform quantization. Uniform quantization partitions the whole space in a uniform manner, and vice versa for the nonuniform quantization. The most common nonuniform quantizers are the Lloyd Max quantizer and the μ law quantizer, as shown in Figure 1.1a and 1.1b, respectively.

Non-Uniform Quantization. The type of quantization in which the space between the quantized levels is non-uniform & has logarithmic relation is called non-uniform quantization. Related Post: Introduction to Signals, Types, Properties, Operation & Application; In non-uniform quantization, the analog signal is first passed through a compressor.
