The method of expansion of set of analyzing frequencies with digital filters, based on frequency selection, was suggested. The way of increasing of measurement precision using this class of filters was investigated. The conformal generalization of structure of filters based on frequency selection and the standard nonrecursive comb filter are the base of this method. This method can be used in different fields of research where the task of determination of hide periodicities is actual.
