Synchronized Swept Sine

Synchronized Swept Sine

Synchronized-Swept-Sine method is a nonlinear system identification method based on “nonlinear convolution” presented by Angelo Farina in AES 108th convention in Paris in 2000. The method can analyze a nonlinear system in the terms of higher order impulse responses using a single swept sine signal with user-defined frequencies and duration. The synchronization of the swept sine, described in [1], allows the phase synchronization of the higher order impulse responses. The higher order impulse responses can be next used, in several ways, to nonlinear modeling…
