In this paper, some applications of the method of correlation analysis for the identification of nonlinear elements with zero-memory property are discussed. The estimation of nonlinear characteristics by correlation methods is generally very difficult. It is well-known that the conventional correlation method gives the statistically linearized characteristics of general nonlinear systems, however further details about nonlinear characterics of elements are not given by this method.
A convenient method for the estimation of the nonlinear characteristics of elements is proposed. An algebraic treatment of the equation for the evaluation of nonlinearity factors an is shown. The method proposed here is very easy and rational in comparison with the method of multiple regression analysis for this problem. Finally, some numerical examples are shown.
