From Fourier to Wavelet Analysis of Time Seriesond order) . of .t. Relation (1.2) tells us that the variance of a time series is decomposed into a number of components, each one associated with a particular .. This is the basic idea in the Fourier analysis of stationary time series. Some references are Brillinger (1975) and Brockwell and Davis(1991).

K. J. Kwon-Chung,John E. Bennettse series show advise specific treatment, differentiated from that of the series which show a higher level of time aggregation. In this article the previous problem is illustrated and an automatic methodology for the analysis of such series is proposed.
