Abstract
This paper presents basic studies of possible advantages when sampling rate is increased up to 1, 600 [Hz] or 2, 000 [Hz] for an accelerometer. The advantages are i) accurate time integration of acceleration data so that displacement or velocity can be numerically calculated, and ii) time synchronization among sensors by comparing their waveforms which are observed with higher temporal resolution. Shaking table experiments are made to compare syntheses displacement from measured acceleration with measured displacement, and taking time synchronization of three sensors which observe actual earthquake is made. It is shown that while it fairly contributes to increase the accuracy of sampling rate, high sampling rate time leads to easy time synchronization of measured data.
