摘要
根据生理信号的特点及目前声卡的技术特性 ,提出了一种利用声卡开发的基于 Director X DSK的生理信号采集与处理系统 .该系统通过对生理信号进行调制处理 ,将信号的频谱移动到声卡频率响应的范围内 ,然后利用声卡进行生理信号的采集 。
This paper proposes a multi channel physiological signal acquiring system based on the characteristics of the physiological signals and sound card. The physiological signals can be acquired with sound card when their spectrums are moved into the frequency response range of the sound card through modulation processing, which provides an inexpensive and effective solution to realize the acquiring and processing of biomedical signals virtually.
