Title: | 可攜式多頻道胃電儀及其臨床應用 | Authors: | 謝銘鈞 | Keywords: | 胃電;微控制器;資料擷取;濾 波器;EGG;micro-controller;data acquisition;filter | Issue Date: | 31-Jul-1999 | Publisher: | 臺北市:國立臺灣大學醫學工程學研究所 | Abstract: | 由腹部非侵入式的記錄胃肌電信號, 通常被稱作EGG 信號,我們設計了前置放 大器、增益20 倍的5 階低通濾波器以及可 切換倍率的次級放大器,配合8 位元的數 位類比轉換介面,將胃電信號儲存於微算 機當中進行分析,提供後續胃電量測的記 錄及研究工具。 Myoelectrical activities of the stomach that is recorded noninvasively from electrodes on the abdomen are usually termed EGG. We designed a preamplifier, a fifthorder low-pass filter with a gain of 20, and a variable-gain amplifier. The EGG signals were digitized by a 8-bit A/D coverter and then analyzed in the frequency domain. This system is helpful for EGG recording. |
