Then the boundary of the current segment is determined, and a new segment-determination procedure starts with the next 128-sample reference window. The major issue of such a method lies in the © The Author(s) 2015 Y. 1007/978-3-662-44284-5_3 33 34 3 Signal Analysis definition of the reference window of an appropriate length to suit a specific VAG signal. For example, if a sudden variation occurs in the middle of a window being tested, the segment boundary would be located at the beginning of the window, rather than the exact position of the sudden variation [17].
