1. 
   noise
   The random fluctuations that are always associated with a measurement that is repeated many times over. Noise appears in astronomical images as fluctuations in the image background. These fluctuations do not represent any real sources of light in the sky, but rather are caused by the imperfections of the telescope. If the noise is too high, it may obscure the dimmest objects within the field of view.

6. 
   Noise
   Any unwanted electrical signals contaminating the signal to be measured. This noise may be electronic noise which is an artefact of semiconductor construction techniques and is not reducible. Alternatively the noise may be caused by environmental factors. This type of noise can be the result of poor positioning or screening of signal wiring. This may result in mains frequency or RF pickup contaminating the required signal.

    Noise
    (Digital cameras and photo printers) A term used in the field of audio engineering to describe interference that can lead to impure sounds and distortion. Noise may occur, for example, as a result of faulty microphones or recording equipment. In digital imaging, noise is a term used to describe the visible effect of interference on the CCD sensor. It appears as unwanted colour spots in an image - especially those taken at night with a slow shutter speed. (Colour noise)

    noise
    this is a technical term meaning any random meaningless data added to either a picture or sound. Whilst noise is usually regarded as undesirable, some forms such as film grain may be actually added to produce a less clean and mechanistic look to an image. (See also boiling)

    Noise
    Electrical interference from adjacent circuitry or injected into power supplies or the ground by other circuit elements, externally induced, or inherent in the circuit elements. Although most obvious in Analogue circuitry (e.g. hiss in an audio amplifier) noise can cause malfunction in Digital circuitry if its peak level is sufficient to exceed the

    noise
    (communications) Any part of a signal that is not the true or original signal but is introduced by the communication mechanism. A common example would be an electrical signal travelling down a wire to which noise is added by inductive and capacitive coupling with other nearby signals (this kind of noise is known as 'crosstalk'). A less obvious form...

    Noise
    Noise can be summarized as the visible effects of an electronic error (or interference) in the final image from a digital camera. Noise is a function of how well the sensor (CCD/CMOS) and digital signal processing systems inside the digital camera are prone to and can cope with or remove these errors (or interference). Visible noise in a digital im ...
