We demonstrate how phase angle statistics can be used to gain confidence in causal relationships and test mechanistic models of physical relationships between the time series.
WebJul 9, 2024 · The transform gets its name from the localized waveform function it uses to convert the signal: the wavelet. The wavelet function must satisfy certain mathematical criteria. The transform itself has an inverse—so we can return to the original signal—and the energy in the transform space can be equated to the signal energy. WebDec 21, 2024 · Wavelets have two basic properties: scale and location. Scale (or dilation) defines how “stretched” or “squished” a wavelet is. This property is related to frequency as defined for waves. Location defines …
