A portable multichannel bioelectrical signal processing system is proposed.Through electrode selection according to the actual needs
the system can collect
process
display and store EEG or ECG signal in real-time. Texas Instruments (TI) Company's ADS1198 is employed as the core for the analog front-end circuit
realizing EEG or ECG acquisition
amplification
isolation and other pretreatment operations. Altera Company's FPGA chip Cyclone Ⅱ EP2C70F896C6 is used for processing the data
displaying waveform in the LCD screen of TRBD_LTM.The system has high accuracy
small size
low power consumption
good practicality and scalability.
