面向脑机接口测试的高精度脑电信号模拟发生系统设计与实现
Design and implementation of a high precision EEG signal analogy generation system for brain-computer interface testing
摘要
Abstract
The basic hardware components of the brain-computer interface,such as electroencephalogram(EEG)acquisition chips or EEG collectors,are gradually being implemented.It is necessary to use an analog signal generator to test and verify the performance.A high-precision microvolt-level EEG signal analog generation system is proposed to address the issues of complexity,bulkiness,and low accuracy in traditional signal generation systems.After experimental verification,this system can generate microvolt-level sine waves,square waves,triangular waves,and EEG signals with a voltage generation error within±1 μV.This meets the performance testing requirements of EEG acquisition chips or EEG collectors and provides a reference for research in brain-computer interface technology.关键词
