摘要：
In this study, a prototype EEG recording and analysis module for biomedical research applications is designed. The design of the system consists of an analog and a digital part. The system has two signal channels, but it can be extended to six channels construction. The analog module involves the following units; an input instrumentation amplifier, gain adjustable amplifier, band-pass filter, and a driven-right-leg- (DRL) circuit. The digital board consists of A/D converter and RS232 communication unit. In order to test system, the circuit simulation and the real-time EEG measurements are implemented. The proposed EEG system can be used in our department's biomedical laboratory. (C) 2006 Elsevier Ltd. All rights reserved.
