Many physical systems exhibit non-linear behaviour. This paper presents the use of new compact multifrequency data measurement signals to identify a linear system with a non-linear distortion at its output. The signals belong to the group of signals exhibiting antisymmetric, or half-period symmetric, properties. A theoretical framework is presented for a non-linear model when using antisymmetric test signals for frequency domain identification. It is shown that the effect of nonlinear distortion is reduced to about 50% by antisymmetric signals. This novel variety of compact multifrequency signals is used in a simulated test of a linear system with non-linear output distortion. A comparison between the new signal and a PRBS signal is reported. |
