Mathematical formulation
A set of diplacement-dependent transfer functions is
derived from the Thiele-Small formulation,
allowing for the dependance of Bl, L and K from the displacement x.
n
different values of x are considered, and around each of them the variation of
the parameters is considered
linear. A separate inverse filter is computed for each of the n not-linear responses, and each sample is
convolved with the proper inverse filter, which is chosen by first computing the estimated
instantaneous displacement x.
