By using the characteristics of two disparate materials (BaTiO3 ceramic and PZT-5H ceramic) on SiO2 glass, we have analyzed shear horizontal wave (SH wave) propagation through a piezo-visco-elastic...

In this paper, some questions of organizing a computer system oriented to supporting processes of processing and analysis of periodic signals are considered. It is supposed that a signal is recorded at the equidistant instants of time with an interva

Some issues of organizing a computer system for the support of processing and analysis of periodic signals are considered. It is assumed that such a support should provide the following facilities: projecting a data processing algorithm with supplyin

Processing and analysis of periodic signals (including noisy ones) are considered to estimate the time position of the corresponding components including the case of frequency modulation. It is proposed to employ four steps of signal processing and a

In this paper, a technique is proposed to process and analyze noisy periodic signals recorded at discrete moments of time. The technique includes two stages: (a) signal quality improvement (processing) with the use of weighted order statistics filter

Median filters are nonlinear and a theoretical analysis of their behavior is very difficult and so are rarely used for the processing of seismic data. However, they are able to preserve steps, sharp discontinuities and edges that are lost using most

We consider some aspects of computer performance of the search for weighted-order statistics in the most general case. In particular, some statistical models of locus of any order statistics in searching sequence are offered. As a consequence of the
