对滤波器耦合矩阵中的极点和零点位置进行编程，以求出表示零点极点的多项式-Coupling matrix of the filter pole and zero position programming has been calculated F (w) E (w) polynomial

Once you input filter coeffiecient you can get frequency responce of filter and drawing that shows the position of pole, zero.-Once you input filter coeffiecient you can get frequency responce of filter and drawing that shows the position of pole, ze
