Abstract
In recent years wavelet analysis has attracted considerable interest as a method of constructing time/frequency decompositions of signals, and it has been suggested that wavelet transforms can be used to estimate time-varying power spectra. In this paper we examine the mathematical framework required for a physically meaningful interpretation of time-varying spectra, and then discuss the extent to which wavelet transforms can be used to estimate such spectra.
