Fabrication of High Precision Pre-amplifier for EEG Signal Measurement and Development of Auto Classification System
뇌파신호 측정을 위한 고성능 전치증폭기 제작 및 자동 신호분류 시스템 개발
Abstract
A high performance EEG signal measurement system is fabricated. It consists of high precision pre-amplifier and auto identification bandwidth unit. High precision pre-amplifier is composed of signal generator, signal amplifier with a impedance converter, body driver and isolation amplifier. The pre-amplifier is designed for low noise characteristics, high CMRR, high input impedance, high IMRR and safety, Auto identification bandwidth unit is composed of AD-converter and PIC micro-controller for real time processing EEG signal. The performance of EEG signal measurement system has been shown the classified bandwidth through the clinical demonstrations.
