阴极射线示波器特别适合将信息显示为电压或电流随时间变化的图表。本文考虑了这种记录方法的优点和缺点。结果表明，当必须从具有空间分离的信号源进行同步记录时，在笛卡尔坐标中解释数据总是很困难，有时甚至是不可能的。描述了一种方法，将 24 个放大通道的输出显示在空间坐标中，并提供指示每个通道的频率、相位和时间关系。简要讨论了该方法在神经生理学问题中的应用，特别是与通过有节奏的感觉刺激在大脑中引起的活动的研究有关。然而，需要强调的是，尽管该装置是为生理应用而设计的，但该方法决不限于这些问题。已经使用该系统对半导体中的电流分布进行了研究，并且认为该方法可以应用于其他电子领域，例如振动分析。
The cathode-ray oscilloscope is especially suited to the display of information as a graph of voltage or current plotted against time. This paper considers the advantages and disadvantages of this method of recording. It is shown that when simultaneous records must be made from signal sources which have a spatial separation, interpretation of data in Cartesian co-ordinates is invariably difficult and sometimes impossible.A method is described whereby the outputs from 24 amplifying channels are displayed in spatial co-ordinates with provision for indicating the frequency, phase and time relations of each channel.Applications of the method to neurophysiological problems are briefly discussed, particularly in relation to the study of activity evoked in the brain by rhythmic sensory stimulation. It is emphasized, however, that the method is by no means confined to such problems, although the apparatus was designed for physiological applications. Studies of the distribution of current flow in semi-conductors have been made using the system and it is thought that there are applications of the method in other fields of electronics, for example, in vibration analysis.
