| Abstract: | Genetic algorithm(GA) is a kind of searching method which simulates the natural evolution.The principle is simple and it is robust and easy to implement.The application of GA in FIR filter design with frequency sampling method is presented.As the sample value of transition bands is obtained by GA,the problem,about which the value obtained by searching for table method is not the most optimal can be solved.Two examples of highpass and bandpass FIR filter design are provided.Experimental results have shown th... |
