内容記述 | The tapping test method for obtaining the response curve of an electromagnetic seismograph by the application of the theory of frequency analysis is described in this paper. A slight tapping is applied to the pendulum, and the motion of the pendulum and the galvanometer activated by it are recorded at the same time. The spectra of both the recorded motions are calculated, and then the magnification, the frequency characteristics and the phase angle of the electromagnetic seismograph are reckoned. | |||||
