Method of analysis of a signal by wavelets

摘要

The invention relates to methods of analysing signals of short duration. …??The invention involves a decomposition using Mallat's algorithm with Daubechies wavelets; at each step, the correlation 201, 202 is carried out both on the signals coming from the correlation at the previous step by the scale signal phi G and on the signals coming from the correlation at the previous step by the signal phi 0. In this way, a homogeneous signal composed of 2p x Np points of analysis is obtained at the pth step. …??In analysis by wavelet, the invention makes it possible to obtain a representation of the results in a homogeneous form which facilitates their interpretation. …IMAGE…
