The quantizer allocates L levels to the task of approximating the continuous range of inputs with a finite set of outputs. The range of inputs for which the difference between the input and output is small is called the operating range of the converter.

What does a quantizer do?

A quantizer is a module that takes control voltage signals and constrains them to a particular set of notes in a modular synthesizer. One of its applications is to make sequences of voltages sound more "musical" than sequences of uncorrelated voltage levels.

What is quantization why it is needed?

Quantization, in essence, lessens the number of bits needed to represent information. ... Lower-precision mathematical operations, such as an 8-bit integer multiply versus a 32-bit floating point multiply, consume less energy and increase compute efficiency, thus reducing power consumption.
