A NEW APPROACH FOR EREQUECNCY RESPONSE FUNCTION ESTIMATION BY BISPECTRUM
Modal Analysis the International Journal of Analyticl and Experimental Modal Analysis V8 N4 Oct 1993 P 301-312，-0001，（）：
A now approach to estimating the frequency response function (FRF) is proposed in this paper. Wo will dernonstate this using the feature that the third-order spectrum is insensitive to Gaussian while nosie (GWN). The theoretical analysis and results of digital simulation and specimen tost show tha estimate H is cioser to the true FRF value tha estimates H1 H2 H3 and H3 under the contamination of GWN with a zero-mean value.
