The practical implementation of themodel implies the application of the authors algorithms for the detection of functional dependence on the basisof spectral analysis.</p>Pricingprice discriminationmonopolyfunctionspectral analysisdigital filteringharmonicЦенообразованиеценовая дискриминациямонополияспектральный анализфункцияцифровая фильтрациягармоника
