Cost-Effective EEG Signal Acquisition and Recording System

Sabbir Ibn Arman, Arif Ahmed, and Anas Syed

Abstract—This paper describes a viable, low cost Electroencephalogram (EEG) signal acquisition device which collects and records the signals in the desktop computer using DSP Processor DS-1104. The main considerations while making such a device are simplicity, ease of use and applicability. The uniqueness of this device is that it uses only three electrodes while most other systems use the 10-20 system of electrode placement which requires 21 electrodes. But the reduction in electrodes must not invalidate the output of the system, which is the EEG signal. For this reason, it is critical that the electrodes are placed in the scalp location where we can observe distinguishable change in the various wave patterns of the EEG signal. The main circuit is made of simple electronic elements. The circuit consists of an amplifier, filter and an opto-isolator. In this paper, EEG signal acquisition principles are discussed, applied, and some suggestions for improving signal acquisition are presented.

Index Terms—EEG, brain computer interface, amplifier, electrodes, DS-1104.
