(third-person singular simple present noises, present participle noising, simple past and past participle noised)
From Middle English, from Old French noise (“a dispute, wrangle, strife, noise"); origin uncertain; according to some, from Latin nausea (“disgust, nausea"); according to others, from Latin noxia (“hurt, harm, damage, injury"); but neither explanation is satisfactory in regard to either form or sense.
noise - Computer Definition
Unwanted disturbances superimposed on a signal and interfering with its integrity. Noise can be introduced by equipment or can be the result of natural phenomena. Noise can take a number of forms, including amplitude noise, cross-talk, echo, intermodulation noise, harmonic distortion, impulse noise, random noise, and white noise.
(1) Extraneous, unwanted signals that invade an electrical or optical system. In electronics, noise can come from strong electrical or magnetic signals in nearby lines, from poorly fitting electrical contacts and from power line spikes. In optics, noise comes from the stray reflections of light that emanate from the various components in the optical system. See signal-to-noise ratio and noise cancellation.
(2) Distortions in analog and digital video images that are caused by a variety of circumstances. The silver grains in the original film create granular noise. Electronic circuits create Gaussian noise. Drop outs and bit errors in digital tapes create impulse noise, and the digitization process creates quantization noise. See Gaussian noise, dynamic noise reduction and artifact.
(3) Distortions in a still image caused by variations in the pixels in the CCD or CMOS sensor. See digital camera.
