Abstract

Electroencephalography (EEG) is a common method of obtaining temporally distinguishable event-related potentials (ERP). The quality of the signal is dependent on several factors, including the selection of the amplifier system and electrode type. The aim of this study is to compare the performance of two electrode types, active and passive, with their respectively optimized amplifier system, in distinguishing an ERP signal. The QuickAmp system was used with passive electrodes, while the ActiCHamp was used with active electrodes. EEG data were recorded by the two amplifier systems in different experimental sessions. In each experimental session, the same participant listened to the same set of acoustically controlled English sentences. Data were obtained from the participant via a 32-channel Easycap (10-20 configuration), through the amplifier, to the BrainVision signal recording software. Based on the analysis using EEGlab, it appears that ActiCHamp reduced noise power, but also yielded lower signal power. The results are preliminary, being from a single participant, but suggest both electrode types can yield comparable signal-to-noise ratios.

优化后的脑电图放大系统中有源电极与无源电极的比较

脑电图(EEG)是一种获得时间可分辨事件相关电位(ERP)的常用方法。信号的质量取决于几个因素，包括放大器系统和电极类型的选择。本研究的目的是比较两种电极类型，主动和被动，与他们各自优化的放大器系统，在识别ERP信号的性能。QuickAmp系统与被动电极一起使用，而ActiCHamp系统与主动电极一起使用。两种放大系统分别记录不同实验时段的脑电数据。在每一次实验中，同一名参与者听了同样一组用声音控制的英语句子。参与者的数据通过32通道Easycap(10-20配置)，通过放大器传输到BrainVision信号记录软件。根据EEGlab的分析，ActiCHamp降低了噪声功率，但也产生了较低的信号功率。结果是初步的，来自一个参与者，但表明两种电极类型可以产生相当的信噪比。
