What is non uniform quantization?

The type of quantization in which the quantization levels are unequal and mostly the relation between them is logarithmic, is termed as a Non-uniform Quantization.

How do you implement non uniform quantization?

One method of performing nonlinear quantization is to apply nonlinearity to prior to uniform quantisation and then apply inverse nonlinearity after quantisation. The nonlinearity can be chosen such that output is equally probable throughout the available dynamic range .

Why we are using non uniform quantization?

The technique of non-uniform quantization described in the paper is readily implemented to improve the steady state accuracy of an existing system, or alternatively for a given design-consistent accuracy, to economize in analogue-to-digital converter bit capacity.
