The fundamental question in wavelet analysis is what conditions we have to impose on a function ψ such that a given signal f ∈ L 2 (ℝ) can be expanded via translated and scaled versions of ψ , i.e., via functions These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
