Abstract:
Noise permeates every field of science and technology and has been instrumental in solving great problems, including the existence of atoms and the origin of the universe. But noise, considered by many as unwanted and mistakenly defined as such by some, has little respectability. The story of noise is a fascinating story filled with drama, and worth telling. We discuss who did what, when, and why, and the historical misconceptions, and why "noise" remains a vibrant and exciting area of study.
Also, while it has always been realized that for many physical situations "noise" is not stationary, most of the historical development has dealt with the stationary case. We present some new ideas as to how to handle nonstationary noise.
