=== Amplitude quantization{{anchor|Quantization}} ===
If a signal is to be represented as a sequence of digital data, it is impossible to maintain exact precision – each number in the sequence must have a finite number of digits.  As a result, the values of such a signal must be [[Quantization (signal processing)|quantized]] into a [[finite set]] for practical representation. Quantization is the process of converting a continuous analog audio signal to a digital signal with discrete numerical values of integers.
