Quantization (physics)         
PROCEDURE TO CONSTRUCT A QUANTUM SYSTEM WHOSE CLASSICAL LIMIT CORRESPONDS TO A GIVEN CLASSICAL SYSTEM
Field quanta; Energy quantization; Quantisation (physics); Field quantum
In physics, quantization (in British English quantisation) is the systematic transition procedure from a classical understanding of physical phenomena to a newer understanding known as quantum mechanics. It is a procedure for constructing quantum mechanics from classical mechanics.

  • 3-bit resolution with eight levels.
  • Comparison of quantizing a sinusoid to 64 levels (6 bits) and 256 levels (8 bits).  The additive noise created by 6-bit quantization is 12 dB greater than the noise created by 8-bit quantization.  When the spectral distribution is flat, as in this example, the 12 dB difference manifests as a measurable difference in the noise floors.

Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements. Rounding and truncation are typical examples of quantization processes.

Quantization

Quantization is the process of constraining an input from a continuous or otherwise large set of values (such as the real numbers) to a discrete set (such as the integers). The term quantization may refer to:
