Beno Zerr Â· ENSTA Bretagne. Bessel functions are used to solve in 3D the wave equation at a given (harmonic) frequency. The solution is generally a sum of spherical bessels functions that gives the acoustic pressure at a given location of the 3D space.
But with wavelet. analysis, we can use approximating functions that are contained neatly in ï¬nite domains. Wavelets. are well-suited for approximating data with sharp discontinuities. The wavelet analysis procedure is to adopt a wavelet prototype function, called an analyzing. wavelet or mother wavelet. Temporal analysis is performed with a contracted, high-frequency version. of the prototype wavelet, while frequency analysis is performed with a dilated, low-frequency version. of the same wavelet.
