Traditional optimization methods, such as Powell's method and the Simplex method, are generally very difficult to design high performance filters with the relative band-width less than 0.15% or more than 10%. In this paper, Genetic Algorithm (GA) is used to design filters that meet these requirements. Two special filters are designed in this paper with the relative band-width as 0.15% and 25%, respectively. The numerical results demonstrate that GA can be used to design filters of superior quality when compared to the filters designed by using Powell's method or Simplex method.
