Abstract

Abstract A stable Electrocardiogram (ECG) acquisition system is designed to be applied to filter out the noisy interferences in patient physiological monitor. In the Electrocardiogram signal transmitting and receiving system, the most important operation is to gather signal and amplify signal, as well as filter out noisy interference and transmit correct original data. Hardware circuits and Transmission lines are often proposed to indicate that they are the serious reasons for generating interference. To use standard 12-lead principle, a stable hardware circuit and FIR digital filter are designed to showcase our study has good results in actual ECG monitor. Additionally, a wireless transmission technology is operated in this novel system to increase the portability and reduce line interference, and the experimental results demonstrate that this design can be applied to the actual ECG monitoring equipment.
