Abstract

PURPOSE: To improve the distorsion in the acceleration waveforms of a vibrating table by obtaining the deviation between the signals, which are produced by a linear operation circuit and which correspond to the pressure difference of a vibrating machine, and the signals, which correspond to the pressure difference of an actual vibrating machine, and by applying the deviation signals as a feedback element.
