A converting technique of EEG's frequency to audio-frequency

Abstract

In this paper, a new technique of converting the frequency of EEG to audiofrequency is proposed. The EEG signal is sampled and converted to digital data, then stored to the digital ring memory successively. Reading out these data with more rapid speed than the storing speed, the iterated waveform of original signal is obtained and consequently the frequency is converted to higher one. Moreover, the possibilities of the extraction of the specific information contained in EEG, through hearing, are experimentally explored.
