La notion d'ondelettes est née parce que l'analyse de Fourier qui dépend des blocs de construction oscillants est mal adaptée aux signaux qui changent soudainement. Une ondelette est grossièrement une fonction qui, avec ses dilates et leurs traductions, déterminent toutes les fonctions de notre besoin. L'ondelette Haar (1910) est la plus ancienne ondelette qui a une application limitée car elle n'est pas continue. Pour s'adapter à l'approximation des données avec des discontinuités nettes, des ondelettes qui pouvaient s'adapter automatiquement à différentes composantes d'un signal ont été ciblées pour une enquête au début des années 1980. C'était en 1989, lorsque Stephane G. Mallat a découvert le concept sous-jacent pour obtenir des ondelettes orthonormiques maintenant connues sous le nom d'analyse multirésolution (MRA). Une ondelette est née par un MRA est connue sous le nom d'ondelette MRA. L'ondelette Haar, l'ondelette Shannon et les ondelettes Daubechies sont parmi les ondelettes MRA. L'ondelette Journe est une ondelette non MRA. La transformée de Fourier de l'ondelette Shannon possède le support minimal et aussi celui de l'ondelette de Journne a le support minimal. Une ondelette orthonormale dont la transformée de Fourier a un support minimal est connue pour être l'ondelette de fréquence minimale supportée (MSF).

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The notion of wavelets came into being because the Fourier analysis which depends on oscillating building blocks is poorly suited to signals that change suddenly. A wavelet is crudely a function which together with its dilates and their translates determine all functions of our need. The Haar wavelet (1910) is the oldest wavelet which has limited application as it is not continuous. To suit for approximating data with sharp discontinuities, wavelets that could automatically adapt to different components of a signal were targeted for investigation in early 1980's. It was 1989, when Stephane G. Mallat discovered the underlying concept for obtaining orthonormal wavelets now popularly known as the multiresolution analysis (MRA). A wavelet arose through an MRA is known as an MRA wavelet. The Haar wavelet, the Shannon wavelet and Daubechies wavelets are some amongst MRA wavelets. The Journe wavelet is a non-MRA wavelet. The Fourier transform of the Shannon wavelet possesses the minimal support and also that of the Journne wavelet has the minimal support. An orthonormal wavelet whose Fourier transform has minimal support is known to be the minimally supported frequency (MSF) wavelet. 92 pp. Englisch. N° de réf. du vendeur 9786200103185
