very good c program for software

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.
