| Noise is anything that is added to the signal between its transmission and reception that is not intended by the source. This can be distortion of sound or . . . static. . . . The concept of noise has been extended to mean any signal received that was not transmitted by the source, or anything that makes the intended signal harder to decode accurately.
Information is a measure of the predictability of the signal, that is the number of choices open to its sender. from John Fiske, Introduction to Communication Studies, 2nd ed., 1990. |
