摘　　要：介绍一种基于TMS320VC54x系列DSP的同步十二导联心电采集系统,该系统采用斩波稳零放大电路,同步采样A/D转换器件,通用串行总线(USB)等新技术,获得了更高的精度,更低的噪声以及更灵活的数据通讯方式。此外,系统还在DSP中实现了部分数据预处理工作。A new architectural synchronous 12-lead ECG acquisition system based on TMS320VC54x series DSP is introduced in this paper. Some new technologies such as chopper-stabilized amplifier, simultaneous sampling A/D converter and universal serial bus (USB) will be well used in this system, which grant a higher veracity, lower noise and more flexible way in data communication. Further more, data pretreatment has also been implemented in DSP.
