WebIf you obtain the CWT of two signals, you can use those transforms to obtain the wavelet coherence, a measure of time-varying correlation. Wavelet coherence for each time instant and center frequency produces a coherence value between 0 and 1 which quantifies the strength of the correlation between the two signals.
