A new method of transfer function determination through solution in time domain is presented. As compared to the linear problem the proposed new formulation of the problem employs five instead of three sequences of unknowns. This makes it possible to bring the errors of adjusted observations closer to white noise and to improve the accuracy of transfer function approximation. In this formulation, however, the problem looses its linearity and one must use a nonlinear instead of linear method of least-squares. The authors propose an economical algorithm of the method of successive approximations. For finding the initial approximation, the use is made of the linear problem solution.
