[MATLAB基础] 请教Matlab 数字滤波器设计 - MATLAB爱好者论坛-LabFans.com

我想问：如果我已知数字滤波器的滤波因子，怎么用Matlab查看对于某个输入序列的滤波结果？比如输出滤波后的序列或者图形
谢谢！

使用filter函数即可实现，filter函数的官方应用解释：y = filter(b,a,X) filters the data in vector X with the filter described by numerator coefficient vector b and denominator coefficient vector a. If a(1) is not equal to 1, filter normalizes the filter coefficients by a(1). If a(1) equals 0, filter returns an error.
