Summary
An important distinction in signal processing is often made between “signal” and “noise.” This is proposed here to be approached via a contrast between “order” and “disorder,” in the sense of a “coherent” or “incoherent” structure in a time-frequency description. Basic classes of signals and noise models are discussed, focusing on what will be mostly used in the rest of the book.
