带有一对传输零点的准椭圆函数滤波器相比切比雪夫型滤波器具备更好的选择性。
The quasi-elliptic function filter with one transmission zero has the better selectivity than the general Chebyshev filter.
利用椭圆函数滤波器较陡的过渡带特性设计前向和后向滤波器，消除由于IIR滤波器造成滤波后的数据相位非线性失真。
A back and forward filter with steeper transitional band was designed of ellipse function. It can remove nonlinear phase distortion caused by IIR filter.
准椭圆函数滤波器的传输零点，可以位于阻带内的任意位置处，这能更加灵活地对滤波器的带外抑制度进行调节，其矩形系数可以做得很高。
The transmission zeros(TZ) of Quasi-elliptic function filter could be placed in any position, so the attenuation out of band is controllable, then a high selection performance could get.
