ABSTRACT:
To analyze short-duration signals by means of an analysis using MARRAT's algorithm with the wavelets of DAUBECHIES, at each step the correlation is done both on the signals coming from the correlation at the previous step by the scale .PHI..sub.O signal and on the signals coming from the correlation at the preceding step by the signal .PHI..sub.O. Thus, at the stage p, there is obtained a homogeneous signal consisting of 2.sup.p .times.N.sup.p points of analysis. This makes it possible, in the method of analysis by wavelets, to obtain a depiction of the results having a homogeneous form making it easier to interpret them.
