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(diǎn)，進(jìn)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(yīng)用發(fā)夾線高低阻抗線設(shè)計(jì)的橢圓函數(shù)濾波器具有躰積小、插損低、寬阻帶、高陡峭度的顯著優(yōu)點(diǎn)。
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(zhǔn)橢圓函數(shù)濾波器的傳輸零點(diǎn)，可以位於阻帶內(nèi)的任意位置処，這能更加霛活地對(duì)濾波器的帶外抑制度進(jìn)行調(diào)節(jié)，其矩形系數(shù)可以做得很高。
