Abstract
OSCILLOGRAPHS, as used in electrical laboratories, are divisible into two classes; namely, first, those that employ mechanical vibratory systems, and second, those that employ no mechanical vibratory systems. In the first class, are the great majority of electrical engineering oscillographs. In the second class are Braun cathode-ray tubes. The paper here presented deals only with the first class, or mechanical vibrators.
