Quantisation (in signal processing) refers to the process of reducing a continuous signal to a set of discrete symbols or integer values. In general, a quantization operator can be represented as |

For example, in digital telephony, two popular quantization schemes are the 'A-law' and 'µ-law', each mapping an analog signal to an 8-bit digital value, but each with a different function f. |
