bandpass circuit

基本解释

In view of parasitic passband in the filtering networks composed of distributed elements, a novel circuit of microstrip bandpass filters is presented in this paper.
针对分布参数滤波网络存在寄生通带问题，本文提出一种新的微带带通滤波电路。
A frequency translation circuit (172-188) abuts the multiple channel bandpass filtered analogue signals in the frequency domain without any guard bands between adjacent channel signals.
频率平移电路（172～188）使得经过带通滤波的若干多通道模拟信号在频域中接邻，而在相邻通道信号之间没有任何保护频带。
