FIR带通、带阻滤波器设计，需要输入截止频率以及容许偏差。(FIR band pass and band stop filter design)

本例介绍直接合成带阻滤波器的方法，n阶滤波器能实现n个传输零点(A direct synthesis technique of a new class of bandstop coupled resonator elliptic filters is presented. Two different coupling schemes, which both include source–load coupling are used. The first coupling and routing scheme is the standard folded structure used in implementing bandpass elliptic filters with transmission zeros using resonators.)
