n.抑止頻帶(阻帶；不透明帶)

There is always a smooth transition between passband and stopband. 通頻帶和抑止頻帶之間總是存在一個“平滑切換點(diǎn)”。

Equation for stopband transmission zeros of such lowpass filter is derived from a new equivalent circuit model. 本文基于新的等效電路模型，推導(dǎo)出了此類低通濾波器的阻帶傳輸零點(diǎn)位置。

The proposed period Defected Ground Structure (DGS) provides the excellent cutoff and stopband characteristics. 設(shè)計(jì)的周期DGS單元結(jié)構(gòu)有非常好的截止和帶阻特性。

Factors affecting the stopband characteristic and applications of the structure are also studied. 并研究了影響阻帶特性的因素及這種結(jié)構(gòu)的應(yīng)用。

It is used in the microwave integrated circuits to achieve size reduction and rejection of ripples in stopband. 用在微波集成電路中，可以減小電路尺寸和抑制阻帶內(nèi)波紋。
