| Abstract: | Aiming at some problems in the detecting instrument of physiological signal,a kind of multi-channel detection system based on general computer is designed,replacing the current acquisition card with the computer sound card by the technology of amplitude modulation(AM),time division multiplexing(TDM),and frequency division multiplexing(FDM).Practical experiment indicates that the system is very useful for scientific research and telemedicine,and it has a very good potential prospect. |
