A simplified instrument for the direct measurement of one point on the response spectrum of the ground motion caused by strong-motion earthquakes is described, and the theory of operation is developed. Determinations of the physical characteristics of two test instruments of a standardized design suitable for large scale production and installation are discussed. Direct comparisons between the instrument results and the spectrum analysis of base accelerations are given, and the conclusion is reached that the device in its present form is suitable for the contemplated application to strong-motion earthquake measurement.
