本論文提出了ECG和EMG擷取系統的雛型設計搭配低複雜度演算法，演算法設計上提出無失真資料壓縮（LDC）、資料傳輸編碼（DTE）和移動平均濾波（MAF）。對於MIT-BIH心律不整資料庫的48種測試樣本中，兩種編碼方式的資料壓縮率（CR）平均分別可達到2.72及2.84。此外，提出的基線飄移消除（BWC）演算法大大節省了97.7％的加法次數，在相同的條件下，測試BW檔案（Bw1）的倍數為0.5時，ECG和EMG訊號的SNR的誤差分別為-0.0279 dB和0.0135 dB。硬體設計方面，將前端電路、微控制器和藍牙4.0（BT4.0）製成電路板（PCB），其中儀表放大器（IA）的共模抑制比（CMRR）為100 dB，並且帶通和帶斥濾波器的頻帶分別設置為0.1Hz-1kHz和60Hz。整體而言，本論文提出的設計有低複雜度的演算法及低功耗BT4.0，因此電池壽命可達到41.6小時。 This work presents a prototype design for ECG and EMG acquisition system with some useful and low-complexity algorithms. For algorithm designs, the proposed device can support a lossless data compression (LDC), a data transmission encoding (DTE), and a moving avenged filtering (MAF). The data compression ratio (CR) of two methods for encoding can achieve to 2.72 and 2.84, respectively for all 48 test patterns of MIT-BIH arrhythmia database. In addition, the proposed baseline wondering cancellation (BWC) algorithm greatly saves 97.7% the total number of additions, and the errors in SNR of ECG and EMG signals are, respectively, -0.0279 dB and 0.0135 dB under the same condition of the test BW file (Bw1) with a multiple number of 0.5.For the hardware design, a front-end circuit, a microcontroller and a Bluetooth 4.0 (BT4.0) are fabricated into a printed circuit board (PCB) where the Common Mode Rejection Ratio (CMRR) of instrumentation amplifier (IA) is 100 dB, and the frequency bands of band-pass and band-stop filters are, respectively, set to 0.1Hz-1kHz and 60Hz. Overall, the proposed design had low-complexity algorithms and adopted low-power-consumption BT4.0 so that the battery life be achieved to 41.6 hours.
