测试测量 ADC简化测量高阻抗传感器
 
Delta-sigma ADCs, with their high accuracy and high noiseimmunity, are ideal for directly measuring many typesof sensors. Nevertheless, input sampling currents canoverwhelm high source impedances or low-bandwidth,micropower signal conditioning circuits. The LTC®2484family of delta sig ...
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 ...
接口技术 XAPP904 - CoolRunner-II特性LCD模块接口
 
There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of L ...
