Description: This work suggests a broadening for an application of a Prony’s least-squares method in case of applying it for an identification of measuring devices transfer characteristics which could be described by oscillatory links. The errors of this method which appear while it is applied in different conditions of a measuring experiment are investigated in this work as well. The recommendations for a number of readings optimization are worked out based on aforesaid. Here is investigated a transfer characteristic measuring time influence on an error of the suggested method. Highs and lows of a suggested method are considered in this work as well.
