a Prediction correlation from adaptive filtering with the number of principal components accounted and correlation with the number of time delays added (while keeping the PCA count to 4). b Predicted displacement from adaptive filtering with different number of principal components. c Presents results from hardware filter and the Matlab model against the reference signal. Hardware filter archive ρ = 0.69).
