Abstract : taking an on - line dynamic measurement system as an example , the influence of the distributive position of the filtering network on the error of dynamic measurement is analyzed . the following design criterion is proposed : in differential dynamic measurement system the filtering network must be located behind the add or minus operation circuit 文摘:通过一个动态在线测量系统实例,分析滤波网络分布位置对系统动态测量误差的影响,并提出对于差动式动态测量系统,滤波网络必须位于和差运算电路之后的设计原则。
