TI公司模拟电路专家撰写的顶级运算放大器设计指南，可惜是英文的。不过还是值得推荐-TI analog circuit written by the top experts Operational amplifier design guidelines, it is a pity that in English. But it is worthy of recommendation

基于 avr ATMEGA 128 利用用查表方式 输出SPWM 波，经滤波后 可观察到 50HZ 正弦信号，可 用于H桥逆变，带有死区时间。

锁相环mc145162的应用，频率可变，已经调试成功-Mc145162 application of phase-locked loop, frequency variable has been successfully debug

本示例说明如何编程 STM32F4xx FLASH。后重置，闪存程序/拭除控制器已被锁定。若要解除锁定，使用 FLASH_Unlock 函数。在编程所需的地址之前, 使用闪存擦除部门功能执行擦除操作。擦除过程从开始的扇区，用于的数计算。然后所有这些部门将拭除一个接一个通过调用 FLASH_EraseSector 函数。此操作完成后，将通过使用 FLASH_ProgramWord 函数执行编程操作。写入的数据，则检查和编程操作的结果存储到 MemoryProgramStatus 变量。

利用ARMA、AR、MA模型，以及周期图等进行系统参数估计-The use of ARMA, AR, MA model, as well as the periodogram estimation of system parameters such as

电机是使机械能与电能相互转换的机械，直流电机把直流电能变为机械能。作为机电执行元部件，直流电机内部有一个闭合的主磁路。主磁通在主磁路中流动，同时与两个电路交联，其中一个电路是用以产生磁通的，称为激磁电路，另外一个是用来传递功率，称为功率回路或者电枢回路。-Motor is to convert between mechanical energy and power of machinery, the DC to DC motor into mechanical energy. Executive Yuan as the mechanical and electrical components, DC motor inside the main magnetic circuit has a closed. The main magnetic flux flowing in the main magnetic circuit, while cross-linked with the two circuits, one circuit is used to generate magnetic flux, called the exciting circuit, another one is used to transfer power, known as the power circuit or the armature circuit .
