摘要
设计基于USB2.0的D/A转换模块,文中对模块的主要芯片、主要原理、接口函数及主要性能进行了介绍。通过取一心电数据通过vc编程将其进行D/A转换,输出波形与原始波形进行比较,较好的实现了回放功能。由此可见,该模块的性能指标达到了设计要求。心电数据回放很好的实现,为一系列心电算法的仿真实践及实时心电监护仪的研制打好了基础。
This design is based on the D/A converter module of USB2.0 whose main chips, important principles,interface functions and major performance are introduced in this papers. With the VC program,we can get a better data redisplay after putting one of the ECG Databases to the D/A converter and comparing the output waveform with the original one.Our work would be very useful for promoting a series of simulation practices of ECG calculations and the development of ECG Monitor.
