| Abstract: | In signal processing, noise is a general term for unwanted (and, in general, unknown) modifications
that a signal may suffer during capture, storage, transmission, processing, or conversion. Sometimes, it can also mean signals that are random (unpredictable) and carry no useful information; even if they are not interfering with other signals or may have been introduced intentionally, as in comfort noise. Noise reduction, the recovery of the original signal from the noise-corrupted one, is a very common goal in the design of signal processing systems, especially filters. The mathematical limits for noise removal are set by information theory, namely the Nyquist–Shannon sampling theorem. |
