flat pass-band
解釋
平通帶-
Based on the fourier series digital approximation method, the optimal design of flat - top and high isolation pass band frequency response interleaver has been studied. at last a solution of high isolation ( > 45db )
用傅立葉級數展開數值逼近的方法進行了高隔離度平頂通帶頻響全光纖奇偶交錯濾波器的優化設計,提出了隔離度大於45db通帶平坦濾波器的製作方案。 -
At the same time, the design of cascaded coupler with a given ratio distribution is proposed, which can lead to higher isolation by suppressing sidelobe. 2. according to theoretical analysis and numerical simulation, the interleaver can show flat - top and high isolation pass band characteristic when the two couplers " ratio is assigned to 15 percent
2 .對全光纖反射式奇偶交錯濾波器進行了理論分析和數值模擬,發現當兩個耦合器的分光比均為15時產生了平頂高隔離度的通帶頻響特性,做了相關實驗,結果與理論分析基本符合。
