It separates and retains the signal features in one or a few of these subbands. Two principally independent methods of time series analysis are used: the T-R periodogram analysis (both in the standard and “scanning window” regimes) and the wavelet-analysis. Wavelets are a relatively new signal processing method. Although it is not uncommon for users to log data, extract it from a file or database and then analyze it offline to modify the process, many times the changes need to happen during run time. I generated 500 white-noise data series with the same time sampling as the Agassiz d18O data from 6000 to 8000 yr BP. Topics in Brain and Cognitive Sciences Human Ethology, Spring 2001.

Then I computed the strength of the strongest peak in the DCDFT spectrum over the I also analyzed the GISP2 d18O data using another popular time-frequency method, wavelet analysis (using the WWZ, Foster 1996, Astronomical J., 112, 1709). The obtained results are very similar. A wavelet transform is almost always implemented as a bank of filters that decompose a signal into multiple signal bands. Time Series Analysis, Fall 2002.
