中文说明:
介绍了一种用Matlab信号处理工具箱进行数字滤波器设计的方法。给出了工具箱中的FDATool 图形用户接口的详细使用方法,用FDATool 进行滤波器设计,可以随时对比设计要求和滤波器特性调整参数,直观简便,在每次改变参 数时,由于计算机的超强运算能力,只需点击设计按钮,新的滤波器立即产生,避免了传统滤波器设计的大量手工运算。并 用他设计出了满足性能要求的低通数字滤波器,实现了对加速度传感器干扰振动信号的滤除,解决了工程实际问题。
English Description:
A method of digital filter design using MATLAB signal processing toolbox is introduced. The detailed use method of the FDATool graphical user interface in the toolbox is given. When using FDATool for filter design, the design requirements and filter characteristics can be compared at any time to adjust the parameters, which is intuitive and simple. Each time the parameters are changed
