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.
