THE SPECTRAL CHARACTERIZATION AND COMPARISON OF NON-STATIONARY PROCESSES.
Abstract
The spectral representation theories of second order stationary, harmonizable, exponentially convex, and normal-type stochastic processes are reviewed and the processes are compared. Locally stationary and asymptotically stationary processes are viewed within the framework of harmonizable and normal-type processes. The concept of a time-dependent spectrum is developed, a general condition for its existence is given, and the time-dependent spectra of harmonizable and normaltype processes are derived. (Author)
