An Auditory Event-Related Potential Encoder

Abstract

This paper presents the development of a simulator for EEG event-related potentials (ERPs) that uses as input parameter essential features that make up the signal, including amplitude, latency, wave width, jitter and signal-to-noise ratio. A database of auditory oddball stimuli signals was used to obtain the main parameters for the ERP simulator. The average of the signals in 9 electrodes was extracted to feed the data into the simulator and the synthetic output signal compared with real data. The results show good similarities between real and synthetic signals. A correlation of 67.4% between the average of the real and synthetic signals was observed. The simulator shows good potential as a tool to generate synthetic ERPs to aid and validate the development of techniques applied to EEG signal processing.
