It is some 50 year since Blackman and Tukey's book on "The Measurement of Power Spectra" appeared. In that time the statistician's interest in spectral methods has waxed and waned.

This talk is intended to remind its audience of the potential of these methods for answering questions about the structure and dependence between time series, and its importance for anyone dealing with time series. The presentation will aim to be accessible to those with little knowledge of the topic, and applications will be taken from many areas including the medical and environmental sciences and economics.
