| Abstract: | This paper introduces two basic methods, describes the advantages and disadvantages of signal processing for EEG, and also analyses the primary, features of DSP, especially TMS320LF2407.Besides,it expounds how to realize the hardware and the software of 16-channel signal processing system for EEG based on the TMS320LF2407 DSP. The system possesses very simple, dependable hardware structure and good flexibility, which can provide solid hardware structure for the software of EEG digital signal processing. The software of the system makes full use of 16-chnannel inter high speed ADC of TMS320LF2407,realizes smoothly to get rid of 50Hz interference and acquires clear and clean 16-channel EEG. |
