Haar Walsh basis. The normalized signals are shown together with the Haar-Walsh basis function that provides a maximal classification; the four figures refer to different scale levels in a decreasing order from fig. 1 to 4. On the x-axis we report the position in bp of the selected region; in the y-axis we report the six signals of the three twin couples (denoted by Cn1, Cn2 and Cn3). The amplitude of the normalized Gaussian peaks is measured along the z-axis. The Haar function that performs the signal classification is also drawn. The level 4 allows an optimal classification of the selected region of the first twins couple. The selected region is not a global classifying region since it does not distinguish between the signals of the second and the third twin couples.
