摘要
提出了一种基于全局优化算法(Global Optimization Algorithm)的FIR(finite impulse response)滤波器设计,本算法通过确定过渡带的最佳采样值,可以得到最大的阻带最小衰减,从而解决了频率采样法设计FIR滤波器不能保证最优的问题。测试结果表明了本算法的可行性和优点。
This paper proposes a method of how to design FIR filter based on Global Optimization Algorithm. The algorithm op-timum sampling values by determining the transitional band, can be obtained the maximum stop-band minimum attenuation, Thus solving the frequency sampling design FIR filter could not be obtained. The test results show feasibility and advantages of the algo-rithm.
