In [[digital signal processing]], '''quantization''' is the process of approximating a continuous signal by a set of discrete symbols or integer values. In general, a quantization operator can be represented as

:''Q''(''x'') = round(''''f(''x))''))

where ''x'' is a real number, ''Q(x)'' an integer, and ''f(x)'' is an arbitrary real-valued function that controls the 'quantization law' of the particular coder.
