영문초록

This paper proposes a new type of active seismo-meter measuring vibration possessing long period and wide dynamic range. In order to lower the natural frequency and expand the detectable amplitude, the sensor with the low natural frequency is realized by using feedback control. Besides, analog feedback control circuit consisted of resistors, capacitors and operational amplifiers possess temperature dependency, while digital feedback control circuit consisted of computer and digital signal processor is temperature independent. In this report, a novel digital feedback control circuit is developed and tested to avoid temperature dependency. It has been demonstrated that the detectable frequency range and the dynamic range of that is expanded.
