We studied the low frequency component about 1 cpm from the rabbit serosa. The component should be removed or ignored in our conclusion. In addition, we created a low power, only 165 ìA, acquisition system to accomplish the portable EGG recorder.application/pdf116290 bytesapplication/pdfzh-TW國立臺灣大學醫學工程學研究所胃電資料擷取省電設計濾 波器EGGdata acquisitionlow power designfilterreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/29531/1/892320B002146M08.pdf
