Fig. 2. Weightings for (A) the first principal component (PC I) and (B) the second principal component (PC II) shown with the proportion of the signal that this component describes. (C) Intensity spectra reconstructed from the vector product of the PC loading scores and the PC weightings. The mean frequencies (MF) for the reconstructed spectra are shown. The angle {theta} is a measure of the relative PC I and PC II loading scores and of the myoelectric frequency.
