A setup composed of a bioanalyser and additional electronic circuits is described allowing to measure the instantaneous frequency and amplitude of the dominant component of EEG activity. Besides recording the above values on paper by means of the EEG apparatus, functions of probability density of both the amplitude and the frequency of EEG activity are estimated on-line during preadjusted time intervals, and displayed on the screen of the bioanalyser. The mutual relationship between instantaneous EEG amplitude and frequency can be expressed in two-dimensional histograms displayed on a memory scope. The system described is suitable for laboratories having no possibility to use general purpose computer on-line.
描述了一种由生物分析仪和附加电子电路组成的装置，该装置能够测量脑电图（EEG）活动主要成分的瞬时频率和幅度。除了通过脑电图设备将上述值记录在纸上外，还能在预先设定的时间间隔内在线估计脑电图活动幅度和频率的概率密度函数，并显示在生物分析仪的屏幕上。脑电图瞬时幅度和频率之间的相互关系可以用显示在存储示波器上的二维直方图来表示。所描述的系统适用于无法在线使用通用计算机的实验室。
