51汇编语言，格式为.chm文件，这个好象就是九十年代初孙涵芳（如果我没记错的话）写的一 本书后附的子程序。子程序不全对，至少有个除法的余数有问题，扩大了2倍，我记不清是哪个了，你把其中的一个左移语句去掉就行了，别的记不得了。欢迎常联系。-51 assembly language format. Chm documentation, It was like the early 1990s-wu (if I remember correctly so) wrote a book attached to the subroutine. Subroutine incomplete right, at least a division of the remaining problems, and expanded two times, I can not remember clearly what is, you put one of these bits removed statement on the visit, other reporters unnerving. Welcome regular contact.

用过采样和求均值技术提高模数转换器的分辨率.pdf-----针对目前单片机内嵌的模／数转换器的分辨率太低，而外接高分辨率成本又太高的情况，提出了用“过采样和求均值”的技术来使在有用的测量频带内的信噪比得到改善，从而提高测量的分辨. 率。并利用 60 - 7 0 /对其结论进行仿真，且在单片机上予以实现，结果表明测量分辨率明显提高。-Sampling and averaging techniques used to improve the resolution of ADC. Pdf----- targeted at the embedded microcontroller A/D converter resolution is too low, while the external high-resolution costs are too high situation, put forward with " Oversampling and Averaging" technology to make useful measurements in the frequency band signal to noise ratio to be improved, thereby enhancing the measurement resolution. rate. And a 60- 7 0/simulation of its conclusions, and in the SCM to be achieved, results show that the measurement resolution has improved significantly.
