Abstract
In comparison with fourier analysis and the classical scheme veyvlet-decomposition, processing signals on the basis of veyvlet-packages in which additional processing high-frequency components a pyramid the analyzed signal therefore the «full» (balanced) tree veyvlet-decomposition turns out is carried out is the most acceptable. The optimum structure decomposition a signal at veyvlet-batch operation gets out by criterion a minimum entropy taking into account additional criterion resolution a signal.
For recognition of EGEG-signals it is convenient to use rated average capacities of their veyvlet-package coefficients which represent informative signs, the least sensitive to change of average power of realization of the recognizable signal, and having the diagnostic importance.
