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 the word is also used to mean signals that are random (unpredictable) and carry no useful information; even if … See more
Signal processing noise can be classified by its statistical properties (sometimes called the "color" of the noise) and by how it modifies the intended signal:
• Additive noise, gets added to the intended signal See moreNoise may arise in signals of interest to various scientific and technical fields, often with specific features:
• Noise (audio), such as "hiss" or "hum", in audio signals See moreAlmost every technique and device for signal processing has some connection to noise. Some random examples are:
• Noise shaping

In electronics, noise is an unwanted disturbance in an electrical signal.
Noise generated by electronic devices varies greatly as it is produced by several different effects.
In particular, noise is inherent in physics and central to thermodynamics. Any conductor with electrical resistance will generate thermal noise inherently. The f…Wikipedia · Text under CC-BY-SA licenseSignal and Noise - Definition and examples — Conceptually
