A signal processing system and computer-implemented method for processing a digital data sequence representing all Input signal to generate a fractal dimension value. The system includes a correlation integral value generation module correlation plot generation module a segmentation module correlation dimension generation module and a control module. The correlation Integral value generation module generates a series of correlation integral values for points Wnk In N-dimensional space corresponding to vectors of said digital data sequence and in particular generates inter-point distance values within each of a plurality of volume elements of said N-dimensional space. The correlation plot generation module generates a correla tion Integral plot comprising a plot of the correlation integral values as a function of said N-dimensional space volume elements. The segmentation module generates from the plot a series of correlation integral plot segments.
