Method
2 – Diagonal Volterra Kernels
lWe start
from a measurement of the system based on exponential sine sweep (Farina,
108th AES, Paris 2000)
lDiagonal
Volterra kernels are obtained by post-processing the measurement results
lThese
kernels are employed as FIR filters in a multiple-order convolution process
(original signal, its square, its cube, and so on are convolved separately and
the result is summed)
