Abstract: After discussing briefly some of the difficulties involved in equalizing in the conventional manner the frequency characteristic of the light modulator previously described by the author, a process is described of equalizing by means of a small drop of oil placed at a chosen point upon the vibrating ribbon. By varying the size of the drop and its location upon the ribbon, a whole series of characteristic curves is afforded from which any desired one may be chosen. The advantages of such a system, as regards the frequency response, factor of safety for the ribbon, and amplification, are described.
