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.
針對分佈蓡數濾波網絡存在寄生通帶問題，本文提出一種新的微帶帶通濾波電路。
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.
頻率平移電路（172～188）使得經過帶通濾波的若乾多通道模擬信號在頻域中接鄰，而在相鄰通道信號之間沒有任何保護頻帶。
