Abstract
A novel signal processing approach is developed in the present study for accurate elevation of the output frequency responses of nonlinear systems to sinusoidal inputs. A simulation study is described, which verifies the effectiveness of the proposed approach. The approach is also applied to analyse experimental data from dynamic testing of rheological properties of a polymer material. The results show that the approach has considerable potential in a wide range of engineering applications.
