摘　　要：研究了用模拟退火遗传算法来设计FIR数字滤波器,并针对算法在寻优过程中,参数搜索缓慢的特点提出了改进方法,该方法在一定程度上提高了算法的搜索性能.并结合FIR低通数字滤波器的设计给出了仿真结果.In this paper a FIR filter is designed based on the genetic algorithm with simulated annealing method. For overcoming the shortcomings in searching process, two improved methods are given. Simulation results show that the convergence efficiency is improved using these two. A simulation result of FIR filter designed on the basis of the improved genetic algorithm with simulated annealing method is given.
