Abstract :
A method for measuring first/second Volterra kernels in the frequency domain is given. For the case where the input signal is a superposition of many sinusoids, the Volterra modeling of a nonlinear system in a discrete frequency domain is given. Using this model and carefully choosing input frequencies, one can measure the first/second Volterra kernels at many points simultaneously. A computer algorithm is proposed, and simulation results that show the efficiency of this method, are given.<>
