A hybrid method of frequency analysis is described by means of which EEG changes related to stimulus-response tasks have been studied. Frequency analysis was carried out using a bank of 20 analog filters by means of which quantitative spectral data were obtained as a function of time. Storing, averaging and statistical analysis of these time-varying spectral data were performed, using a general purpose computer (PDP 11-20). The method proved to be useful for analysis of the non-stationary properties of EEG changes related to certain behavioural events.
本文描述了一种频率分析的混合方法，通过该方法研究了与刺激-反应任务相关的脑电图（EEG）变化。频率分析是使用一组20个模拟滤波器进行的，通过这些滤波器可获得作为时间函数的定量频谱数据。使用通用计算机（PDP 11-20）对这些随时间变化的频谱数据进行存储、平均和统计分析。该方法被证明对于分析与某些行为事件相关的脑电图变化的非平稳特性是有用的。
