根据电能表的功能和误差精度的需求，我们选用了ST公司STM32的增强型系列STM32F103xx，最高工作频率为72MHz。在程序设计上除了完成快速数据处理工作以外，还针对系统非线性失真进行了修正和补偿-According to the energy meter function and the needs of the error accuracy, we chose the ST companies, the STM32 Performance line STM32F107xx, the maximum operating frequency of 72MHz. In addition to complete the fast data processing in the program design, but also for nonlinear distortion correction and compensation
