| Abstract: | This paper proposes to apply the correlation analisis approach to identify frequency responses of mathematical models in discrete time domain. A example is given in order to demonstrate the efficien- cy of the appoch. The calculation results have shown that identification accuracy of the method is very high and so satisfactory. The method can be used both in linear and in nonlinear systems. |
