摘要
主要对微弱电流检测的测量电路原理进行了研究,同时用分压反馈电路给出了电路图,应用数字滤波进行数据采样,并进行了电路误差分析,并用软件实现这一功能。这种测量电路有着较广泛的应用前景。
It researched the theory about measuring circuit of faint current measurement, and supplied the scheme of system structure. It realized the foundation with software which has been added to FIR digital filtration. This kind of measuring circuit has an extensive use.
