An improved version of a previously presented computer analysis for EEG is described. The basic process used in the analysis is the classification of waves according to duration (frequency) and amplitude. The unique aspect of the improved system is the distinction between "simple" waves and "composite" waves, which are slow waves with superimposed higher frequencies. The computer program makes this "decision" on the basis of wave symmetry.
