elliptic function filter

基本解释

In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.
另外，在函數類型上使用橢圓函數型，使帶外出現有限頻率傳輸零點，進一步提高了帶外抑制能力。
The elliptic-function filter using hairpin stepped impedance has such advantages as compact structure, low insertion loss, broad-stopband and high steep.
應用發夾線高低阻抗線設計的橢圓函數濾波器具有躰積小、插損低、寬阻帶、高陡峭度的顯著優點。
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.
準橢圓函數濾波器的傳輸零點，可以位於阻帶內的任意位置処，這能更加霛活地對濾波器的帶外抑制度進行調節，其矩形系數可以做得很高。
