多道数据采集系统设计

摘要

The paper discusses design and realization of multi-channel data collection system based on USB2. 0. The system hardware and software design was introduced. The performance tests with histogram method and FFT method were carried out. The testing result indicates that the system function is stable and the accuracy of conversion is high.%文章讨论了基于USB2.0的多道数据采集系统设计与实现.介绍了系统的硬件及软件设计方法,给出了其性能测试结果.结果表明:系统性能稳定,转换精度较高.
