Abstract :
In this paper, an optimization design method of FIR digital filter based on frequency sampling technique with introduction of particle swarm optimization (PSO) is proposed. The rate of the passband ripple to the stopband attenuation is regarded as optimization goal, through optimized the interpolation of transition on band and the algorithm is designed by global optimized capability of PSO. Experimental results have shown that the design is both feasible and effective, and its performance is better than that of traditional methods
