Dsp-based Ecg Monitoring Key Technology Research

The technology of digital signal processing has made great progress with the development of information science and chip technology since it was born in 1960s.HHCE (Home Health Care Engineering) is a tendency of telemedicine. The convenience of HHCE is custody and recording some physiological parameter. Portable ECG signal gathering & monitoring instrument is the fore device of HHCE.In the thesis, I put forward a portable ECG signal gathering& monitoring instrument based on DSP instrument. In the first chapter of the thesis, some basic problems about DSP systems are discussed and summarize the board designed by author. Then, power circuit, storage circuit, Serial communical ion circuit and CPLD circuit are mainly discussed. Based on these processes, adaptive filtering of ECG is studied and tested on the DSP board, then the results of experiments are analyzed. At last, the future applications of DSP technology and ECG are made.
