Quantization

n. (Mathematics) allocation of discrete values (not successive) to a particular variable (also quantisation)

Quantization is the procedure of constraining something from a continuous set of values (such as the real numbers) to a discrete set (such as the integers). Quantization in specific domains is discussed in:Quantization (signal processing)Quantization (image processing)Quantization (sound processing)Quantization (music)Quantization (physics)Quantization (linguistics)

Noun
1. the act of dividing into quanta or expressing in terms of quantum theory
(synonym) quantisation
(hypernym) division
(derivation) quantize, quantise

A process in which the continuous range of values of an analog signal is sampled and divided into nonoverlapping (but not necessarily equal) subranges, and a discrete, unique value is assigned to each subrange. Note: An application of quantization is its use in pulse-code modulation . If the sampled signal value falls within a given subrange, the sample is assigned the corresponding discrete value for purposes of modulation and transmission . (188 )
