The Influence of Frequency Response Function Estimators on the Approximation of Modal Parameters

It has been shown that the various Frequency Response Function (FRF) Estimators will account for certain types of measurement bias. The motivation behind these estimators is to obtain a more accurate FRF from which modal parameters are obtained. This research addresses the practicality of using a specialized FRF Estimator by comparing the accuracy of the resultant modal parameter estimates.

This study of single input/single output systems focuses on the use of scaled FRF Estimators as applied to bivariate data with correlated contaminants.
