What Is Meant By Companded Quantization?

1.	What Is Meant By Companded Quantization?
Answer» Companded QUANTIZATION maps the input through compressor function. This function expands the probability to the high level regions. These regions are close to the origin. These regions are compresses the CORRESPONDING lower probability regions that are away from the origin. The output of Companded Quantization is resulted by using uniform quantizer. An EXPANDER function is USED to transform the quantized VALUE.
