摘要：

Most parametric frequency-domain estimation methods, applied to linear time invariant systems, do not take into account the disturbing input noise. It is shown that these estimators can still be used to obtain unbiased estimates from noisy input-output measurements if an input signal with a constant signal-to-noise ratio is used. By means of an experiment in the field of modal analysis, it is demonstrated that a multisine excitation is a handsome tool to create an input signal with a constant signal-to-noise ratio, even when the disturbing noise at the input is strongly colored. © 1990 IEEE
