摘要
为解决阻容电路特征阻值测试时间长、误差大的问题,对典型的阻容并联电路的特性进行了理论分析,提出了一种等时间间隔采样法,应用该方法,只需要等间隔采样三个测量值,便可以计算出该电路的特征阻值;讨论了特征阻值测试仪的误差源和减小误差的方法;实验验证,等时间间隔采样法的测量效率是直接测量法的5倍以上。
To reduce the measuring time and errors of characteristic resistance measuring of Resistor-Capacitor circuits,after some theoretical analysis on circuit parallel connected by a resistor and a capacitor,we deduced a measuring method and named it sampling in equal time interval method.Using this measuring method,we just need to sample 3 values in equal time interval,then we can calculate the characteristic resistance of the circuit.We also discussed the source of errors and found ways to reduce the errors of the results.The experiments improved that the new measuring method can work 5 times faster then traditional ways.
