Description: 此程序为本人编写的神经网络法设计1型FIR滤波器的程序,读者读此程序后,可以很深刻地理解如何用BP网络和LMS算法来设计滤波器。
只需更改程序中的H值,即可生成各种低通,高通,带通,带阻滤波器。程序运行结果可得到滤波器系数,幅频曲线和衰减曲线。
可通过更改迭代步长和误差极限来调整滤波器特性。-I prepared for this procedure the neural network type 1 FIR filter design procedures, the reader after reading this program, it is a profound understanding of how to use BP network and the LMS algorithm to design filters. Just change the procedures in H values, to generate a variety of low-pass, high pass, band-pass, band stop filter. Program is running the results of available filter coefficients, amplitude-frequency curve and the attenuation curve. Can change the iteration step size and error to adjust the filter characteristics of the limit. Platform: |
