With the increasing use of [[computer]]s the usage and need of [[digital signal processing]] has increased. In order to use an analog signal on a computer it must be digitized with an [[analog to digital converter]] (ADC).

Sampling is usually carried out in two stages, [[discretization]] and [[quantization]]. In the discretization stage, the space of signals is partionedpartitioned into [[equivalence class]]es and discretization is carried out by replacing the signal with representative signal of the corresponding equivalence class.

In the quantization stage the representative signal values are approximated by values from a finite set.
