Abstract: In the paper we consider some questions of support of designing and escorting one-dimensional WOS filters by means of the window interface. Weighted order statistics (WOS) filters are widely used for processing the signals which can be registered as time series. A special case of such a filter is a median one. An estimation of WOS filters behavior is rather complicated by virtue of its nonlinearity. At the same time, their response appreciably depends on the design (values of weights, size of the aperture or a window of the analysis, sequence of operations in multistage process of a filtration). That is, the problem of creation of corresponding system is actual.

Keywords: technologies of counting, weighed order statistics filters.
