Impulse Response Measurement of Nonlinear Systems: Properties of Existing Techniques and Wide Noise Sequences
Methods for measuring impulse responses have problems when the system under test contains elements that are nonlinear. Before exploring a new approach to the problem, the authors explain the effects of nonlinearities on traditional impulse response techniques. They show how wide maximum-length sequences have advantages over existing techniques for measuring the linear component of the response. Then they illustrate how these advantages can be applied to multiple noise sequence measurements to measure nonlinear behavior using the diagonal Volterra series expansion of the impulse response of general nonlinear systems. This approach better characterizes the system being measured.
