Abstract
In this paper there is described a test device for showing frequency response curves visually wherein the recording apparatus is a cathode ray tube. In this method a sine voltage is used for the deflection of the beam, and the capacity of the rotating condenser is varied sinusoidally. The form of the plates of this rotary condenser is described, and several examples of resonance curves photographed on the screen of the cathode ray tube are given.
