Study on the Optimum Design of the High-Order Multi-Band-Pass Filters

本文详细讨论了FIR线性相位滤波器幅频特性与余弦基神经网络算法之间的关系 ,证明了神经网络的收敛定理 ,给出了高阶多通带滤波器的设计实例 .

This paper discusses in detail the relations between the amplitude frequency characteristic on the FIR filters with linear phase and the algorithm of the neural networks,proves the convergency theorem of the algorithm,and presents the design examples of the high order multi band pass filters.The results show that the algorithm is efficient and excellent in the design field of the quasi ideal multi band pass filters.
