NOISE (STATISTICAL)

Statistics Directorate    
Definition:
A convenient term for a series of random disturbances borrowed through communication engineering, from the theory of sound. In communication theory noise results in the possibility of a signal sent, x, being different from the signal received, y, and the latter has a probability distribution conditional upon x. If the disturbances consist of impulses at random intervals it is sometimes known as “shot noise”.
