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.
