| Abstract: | Objective Ensemble average is a basic and effective method in evoked potential(EP) signal application for eliminating random noises. However, it may cause the merge of multi-peaks of latency. Methods The method for separating the merged peaks in ensemble averaged EP signals by analyzing and correcting the poles of EPs was reported. Results and conclusions The data analysis shows that this method is useful in clinical application with its high resolution and improving the accuracy and the reliability in detecting the latency of evoked potentials. |
