Web其中窗函数设计法在学校课堂中是重点讲解的,提到FIR滤波器肯定会想到hamming、kaiser窗,但是实际应用中却很少使用,因为如果采用窗函数设计法,达到所期望的频率响应,与其它方法相比往往阶数会更多;而且窗函数设计法一般只参照通频带wp、抑制频带ws和 ... http://www.360book.com/down/122-1044617-1.html Webexample. b = cfirpm (n,f,fresp) returns a length n +1 FIR filter with the best approximation to the desired frequency response as returned by the fresp function, which is called by its function handle ( @fresp ). b = cfirpm … cvs weight loss
