    • An electroencephalogram measuring apparatus and method. The electroencephalogram measuring method includes detecting electroencephalogram data of an experimentee, amplifying the detected electroencephalogram data, and converting the data into a digital signal. Also, provided is a high-speed Fourier transforming the converted digital electroencephalogram data, calculating an output value for each frequency of the Fourier transformed electroencephalogram, calculating an output value for each frequency of the electroencephalogram for a predetermined time interval and calculating a relative output value for the ground state of the experimentee. Further provided is comparing the calculated relative output value for each frequency for each predetermined time interval for the ground state of the experimentee, with a predetermined value.
    • 脑电图测量装置及方法。 脑波测量方法包括检测实验者的脑电图数据,放大检测到的脑电图数据,并将数据转换为数字信号。 此外,提供了对转换的数字脑电图数据进行高速傅立叶变换,计算傅里叶变换脑电波的每个频率的输出值,计算预定时间间隔的脑电图的每个频率的输出值,并计算相对输出值 为实验者的基础状态。 进一步提供的是,将每个预定时间间隔的每个频率的计算出的相对输出值与实验者的基态相比较,具有预定值。
