Web1White noise is a traditional term in signal processing to refer to stochastic processes made of independent random variables. The reason for this name is that the spectrum of these stochastic processes (signals) is at, i.e., all frequencies have the same magnitude. It just so happens that this is what the spectrum of white light looks like. WebIn probability theory, a Subordinator is a stochastic process that is non-negative and whose increments are stationary and independent. Subordinators are a special class of Lévy process that play an important role in the theory of local time. In this context, subordinators describe the evolution of time within another stochastic process, the subordinated …
