title: Decomposition of Evoked Potentials using Peak Detection and the Discrete Wavelet Transform.
abstract: A new method of viewing evoked potential data is described. This method, called the peak detection method, is based on singularity detection using the Discrete Wavelet Transform. The peaks and troughs of raw Visual Evoked Potential data are identified and characterized using the algorithms of this method, resulting in a linear decomposition of the recording into sets of individual peaks. The individual peaks are then added together, averaged and compared to the ensemble average signal. The peak detection method correlates strongly to the ensemble average showing that this method retains the same evoked potential signal profile.
