Design of FIR Filters with Differential Evolution
Frequency sampling method is one of the usual methods in FIR digital filter design. In frequency sampling method the value of transition band samples are usually obtained by searching for table. However, the value obtained by searching for table can not be ensured to be optimal. In this paper a new application of Differential Evolution (DE) to frequency sampling method is introduced and its performance is compared to that of Genetic Algorithm(GA). Experimental results have shown that the value of transition band samples obtained by DE can be ensured to be optimal, also, it is seen that DE is significantly faster than GA for finding the optimum filter.
