单片机编程 DA与AD转换
计算机应用中，有时需处理的信息不是数字量，而是一些随时间连续变化的模拟量，甚至是一些非电量，如温度、压力、速度等。模拟量的存储处理困难。首先将非电的模拟信号变成与之对应的模拟电信号，这要通过各种传感器来完成。计算机可处理的信息均是数字量（电脉冲信号）1和0，必须把要处理的模拟电量转换成数字化的电信号， ...
通信网络 光纤与光接入网知识汇总
第一讲 光纤的分类 一， 光纤的分类 光纤是光导纤维（OF：Optical Fiber）的简称。但光通信系统中常常将 Optical Fibe（光纤）又简化为 Fiber，例如：光纤放大器（Fiber Amplifier）或光纤干线（Fiber Backbone）等等。有人忽略了Fiber虽有纤维的含义，但在光系统中却是指光纤而言的。因此，有些光产品的说明中，把f ...
测试测量 运算放大器稳定时间的测量
The AN10 begins with a survey of methods for measuring op amp settling time. This commentary develops into circuits for measuring settling time to 0.0005%. Construction details and results are presented. Appended sections cover oscilloscope overload limitations and amplifier frequency compensation ...
测试测量 基于Multisim 10的矩形波信号发生器仿真与实现
在Multisim 10软件环境下，设计一种由运算放大器构成的精确可控矩形波信号发生器，结合系统电路原理图重点阐述了各参数指标的实现与测试方法。通过改变RC电路的电容充、放电路径和时间常数实现了占空比和频率的调节，通过多路开关投入不同数值的电容实现了频段的调节，通过电压取样和同相放大电路实现了输出电压幅值的调节 ...

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC se ...
