The approaches that do not use the synthesis of the entire series Farey, allowing to solve the problem of "failure" combination frequencies frequency converter only on the basis of the synthesis of the next component of the nonlinear frequenc operating frequencies conversion systems. Methods for finding the parameters of Raman noise, straight pass through the "failure" point are proposed. We prove that the area of the nomogram, free from interference of combination, is a quadrangle.</p>Frequency conversioncombinational componentsinfinite fractionsFarey seriesПреобразование частотыкомбинационные составляющиецепные дробиряд Фарея
