FIELD: metrology, methods (indirect methods) for experimental estimation of the dynamic characteristics of measuring means and elements of automatic control systems. SUBSTANCE: the method consists in the fact that one and the same dynamic effect is simultaneously applied to the input of the examined and reference objects, the respective output signals of objects are simultaneously fixed, which then are subjected to Laplace transformation, after that the ratio of the above transformations is found, and the transfer function of the examined object is determined as the product of the obtained ratio and the transfer function of the reference object. EFFECT: enhanced accuracy, operativeness and reduced expenditures connected with measurement of the transfer functions of objects. 33 dwg
