摘要
提出一种用简单整系数数字滤波器处理涡街信号的方法,滤波计算通过加减法实现,避免了乘法运算,计算量小,实现方便。
A new processing method by simple integral coefficient digital filter is presented in this paper.The calculation can be realized by addition and subtraction,avoid multiplication.The measurement results prove that this method has stronger antinoise ability and higher accuracy of measurement.It provides a new way for SCM to use digital filter instead of analog filter.
