Abstract :
The frequency range of the rapid record oscillograph has been extended beyond the natural frequency of the vibrating galvanometer string by the insertion of electrical networks in the circuit to equalize the natural characteristics of the string. An oscillograph using a string equalized to more than 10,000 cycles is described in this article.∗ — Editors.
