介绍了一种用于复杂慢波连续频率分析的自动装置。振动杆用作调谐滤光片，通过外差电路连续选择其幅度被记录的频率。给出了该仪器在脑电图仪中的应用实例。
An automatic device for continuous frequency analysis of complex slow waves is described. A vibrating bar serves as the tuned filter element which, through a heterodyne circuit, selects successively the frequencies whose amplitudes are recorded. Some examples are given of application in electroencephalography for which the instrument was developed.
