An Automatic Low Frequency Analyzer

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.
