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 of noise is quantisation noise, such as the error between
the true colour of a point in a scene in the real world and its representation
as a pixel in a digital image.
