elliptic function filter

基本解釋

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(shù)類型上使用橢圓函數(shù)型，使帶外出現(xiàn)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(fā)夾線高低阻抗線設計的橢圓函數(shù)濾波器具有體積小、插損低、寬阻帶、高陡峭度的顯著優(yōu)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(shù)濾波器的傳輸零點，可以位于阻帶內(nèi)的任意位置處，這能更加靈活地對濾波器的帶外抑制度進行調(diào)節(jié)，其矩形系數(shù)可以做得很高。
