摘要
The invention relates to a process for determining an averaged frequency-dependent transfer function for a perturbed linear time-invariant system by means of an evaluation device, wherein the process comprises providing frequency-dependent reference signals derived from excitations input in a linear time-invariant system, providing frequency-dependent measuring signals for the linear time-invariant system associated with the frequency-dependent reference signals, and determining an averaged frequency-dependent transfer function for the linear time-invariant system, in that, using signal deconvolution of mutually associated measuring and reference signals, frequency-dependent transfer functions are determined and the frequency-dependent transfer functions are averaged, and wherein during determination of the averaged frequency-dependent transfer function at least a part of the determined frequency-dependent transfer functions is included in the averaging corresponding to a respectively associated frequency-dependent weighting. Furthermore the invention comprises an evaluation device for determining an averaged frequency-dependent transfer function for a perturbed linear time-invariant system and a computer program product.
