本文介绍了一种用于俭测EEG瞬态ST’s(峰及快速变化的波形)的简化方法。这个检测器由两部分组成。第一部分是差分滤波器(即电流取样结果与已得到的给定的一系列取样结果之差),从而增强了ST’s的主要的频率分量,可以看作是曲线上升持续时间的综合性计算器;第二部分由一乘法器组成,它的输入就是差分滤波器的输出,并略有延迟,因而就使曲线略有平滑(低通滤波)。为了对 This article presents a simplified method for measuring EEG transient ST’s (peaks and rapidly changing waveforms). This detector consists of two parts. The first part is the difference filter (ie, the difference between the current sample and the given given series of samples), so as to enhance the main frequency components of ST’s. It can be regarded as a comprehensive calculator for the duration of curve rise. The second part consists of a multiplier whose input is the output of a differential filter with a slight delay, thus making the curve slightly smoother (low-pass filtered). In order to right
