具有桥式结构的传感器很多，如利用应变原理、磁电阻原理和其他变电阻原理的传感器，可以实现对压力、位移、加速度、磁场等物理量的测试。这种结构的差分输出可以增加灵敏度，也有一定抵消外加干扰的能力。而且有的虽不是差分输出，比如电阻分压式的输出，可以认为是“半桥”，我们还可以人为的加上另一半，即加上一对精密电阻和一个电位器组成另一个分压电路，形成差分输出。每次调节电位器使差分输出为0，抵消零磁电压。-Bridge structure with many sensors, such as the use of contingency theory, the principle of magneto-resistance and other variable resistance sensor principle can be achieved on the pressure, displacement, acceleration, magnetic field, such as physical tests. The structure of the differential output can increase sensitivity, but also have some ability to offset the additional interference. And some is not a differential output, such as pressure resistance of the output type, you can think is

vhdl状态机设计,文件简单详细易懂，可以使用在交通灯，文件配置等系统上。(vhdl state machine design, simple, detailed and easy to understand, you can use the traffic light system file configuration file.)

基于fpga状态机的交通灯设计，亮灯时间自己修改，程序简单易懂。(Traffic light design based on FPGA state machine, light time self-modifying, the program is simple and easy to understand.)
