轴孔测量中的一种数字滤波器的设计

Design of A Digital Filter for Shaft Hole Measurement

对现有轴孔测量仪进行改造,采用数字信号处理技术设计FIR数字滤波器,对测量信号实行软件滤波,替代原有的硬件滤波电路。测试结果表明,该数字滤波器可以满足轴孔测量的要求。

A FIR digital filter is designed with digital signal processing technology.The measurement signal is processed with software filter instead of hardware filtering circuit.The result shows that the FIR digital filter can meet the requirement of shaft hole measurements.
