Figure 2

Wavelet spectra. The diagrams show exemplary the wavelet spectra of all three MMG- and MTG-signals of subject (A) (left) and subject (B) (right) during one trial of isometric interaction at 80% of the MVC. The right scale describes the power. The left panel displays the summation of the power in the wavelet spectrum over time, thus, is equivalent to a smoothed PSD.
