Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Filtering in the space of probability additive mixture of eccentric quasideterminants signal-to-noise Yu.M. VESHKUR TSEV, N.D. VESHKUR TSEV, D.A. TITOV Built a filter using the characteristic function of A. Lyapunov and trigonometric functions the inverse sine to work in the space of probabilities. Made qualitative and quantitative analysis of the algorithm of the filter using statistical modeling. For example, the filtering additive mixture of eccentric quasideterminants signal and white noise set the filter on average 30 times stronger suppresses noise than signal. Filter efficiency is high when the ratio signal/noise at the input unit and many orders of magnitude less. According to its characteristics, the filter has advantages over the perfect filter. It can find application in vibro-acoustic diagnostics for isolation of vibration from noise. Keywords: characteristic function, filter, eccentric quasideterminant signal, noise suppression, efficiency, probability, entropy, diagnostics, signal/noise.
