Engineering Physics Annotation << Back Multysign parametric selection of the signals Yu.P. VAGIN, Yu.V. PUZANOV Approach to the theoretical analysis of the multi sign selection of the helpful signals and noise is discussed. The notion of the selection signature is introduced. It is showed that the signal signature as the noise has a symmetrical structure. Fore the relation of the signatures to everybody of them the weight is dedicated. The weight is pro rata to the logarithm of the likelihood relation. In the report the numerical selection’s characteristics are specified from the symmetrical notions. Keywords: Signals, noise, selection, the selection sign, weight, the likelihood relation, the selection criterion, operating character. E-mail: Krolli@inbox.ru
