【摘要】：介绍了一种便携式多路微弱医学生物电信号处理系统,用户可根据实际的需要对电极进行选择,从而实现对脑电或心电信号的实时采集,进而对其进行数据处理并显示波形和存储数据。该系统采用德州仪器(TI)公司的ADS1198为核心的模拟前端电路实现脑电或心电信号的采集、放大、隔离等预处理操作,利用Altera公司的FPGA芯片Cyclone Ⅱ EP2C70F896C6对数据进行处理,并在TRDB_LTM液晶屏上显示波形。该系统精度高、体积小、功耗低,具有较好的实用性和可扩展性。
[Abstract]:This paper introduces a portable multi-channel weak medical bioelectric signal processing system. The user can select the electrode according to the actual needs, so as to realize the real-time acquisition of EEG or ECG signal. Then the data is processed and the waveform is displayed and the data is stored. The system uses ADS1198 of Texas Instruments (TI) Company as the core analog front-end circuit to realize the preprocessing operation of EEG or ECG signal acquisition, amplification, isolation and so on. The data are processed by FPGA chip Cyclone 鈪，
