Cross wavelet analysis

WebAug 2, 2024 · Cross-wavelet analysis. Wavelet analysis is a signal processing tool used to identify frequencies, or harmonics, which are present in a time series and contribute to its variance over time (Grinsted et al., 2004; Torrence & Compo, 1998). The technique has the advantage of highlighting harmonics which are intermittent in time, which is a useful ... WebThis bias also affects the cross-wavelet, which can be used to determine the time- and frequency-resolved relationship between two time series. The new version of biwavelet implements the bias-correction developed by Veleda et al. (2012). The bias does not affect the wavelet coherence, however.
