In order to understand the benefits and limitations of '''digital signal processing''' ('''DSP''') it is important to understand the distinction between continuous and [[discrete]] signal representations. In the Synth DIY world, much use is made of the terms [[analog]] and [[digital]] without any clear explanation of the very different assumptions that underpin those terms. |

A ''signal'' can be defined as any function that conveys information about the state of a physical system. This is usually represented as a variation of values over time or space. Signals are represented mathematically as functions of one or more independent variables. |
