【Abstract】 This paper proposes a method of how to design FIR filter based on Global Optimization Algorithm. The algorithm optimum 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 algorithm.更多还原
