摘　　要：多输入通道之间的相位误差是数据采集系统的重要问题之一。采用六输入通道模数转换器件AD73360和数字信号处理器TMS320F2812设计了多通道数据采集系统,实现了两者之间的接口电路和通信程序设计。该系统可用于多路输入信号的同步采样,实验证明了系统的有效性。Phase delay amony the conversions of multi-channel is one of the important problems for data acquisition system. In this paper, a muhi-channel data acquisition system using six input channel A/D converter AD73360 and digital signal processor TMS320F2812 is proposed, including the interface between them and DSP＇s software. This system can be used in simultaneous sampling of multi-channel input signal. The experiment demonstrates the effectiveness of this method.
