Unformatted text preview: Outline of the Lecture Outline of the Lecture Nonlinear System Identification Nonlinear System Identification Nonlinear Kernels Volterra Series Wiener Nonlinear Kernels Volterra Series Wiener Series Series Volterra and Wiener Kernels Volterra and Wiener Kernels Characterize Linear and Characterize Linear and Nonlinear Systems Nonlinear Systems In a black-box model, we try to describe a system well enough to predict its responses without knowing what is inside the system. If the black box is linear, then we can describe the system fully with the impulse response, as any stimulus is a sum of impulses. The impulse response D(t) is the reaction to a very short stimulus at time zero. One can use this model to estimate (r est (t)) the response of a linear system to stimulus s(t): r e s t t ( 29 = ρ + δ τ ∆ τ ( 29 σ τ - τ ( 29 ∞ ∫ The impulse response L(t) is the reaction to a very short stimulus at time zero. One can stimulus at time zero....
