Its applications have been developed in fuzzy and adaptive control method used in washing machines. To date, technologies of computers with high speed and ADC (Analog Digital Converter) with wide dynamic range have been advanced. Therefore, the digital feedback control method has enough potential to be employed to a servo-type seismometer instead of its analog feedback circuit. However, to use the digital feedback control, the problems to be overcome still remain. Those are the dynamic range and the data acquisition speed of ADC/DAC (Digital Analog Converter). This paper proposes an idea to obtain ADC/DAC with wide dynamic range and high-speed data acquisition. In a case of DAC, we use two devices for one data output. One is used to convert upper-half bits of the data and the other is for lower-half bits. ADC also has the same situation. By the above-mentioned method using the two devices with smaller bit-width, the higher data-acquisition speed and the data with a wider dynamic range will be obtained. Now, we will try to develop a PID digital feedback control circuit using the method. The method is patent pending.", "subitem_description_type": "Abstract"}]}, "item_4_description_6": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description":
