带频 meaning in English
band frequency
Examples
- This bandwidth is twelve times greater than that required for ssb fdm , and six times greater than the bandwidth required for double sideband fdm
这个宽带,比单边带频分多路复用所需要的带宽大12倍,比双边带步分多路复用所需要的带宽大6倍 - In addition , the pcs - g50 can achieve a maximum bandwidth of 4 mb s with an ip connection , and up to 768 kb s with an isdn connection using an optional pcsa - b768s isdn unit
此外， pcs0 - g50在ip网络连接的带频最高可达4mbps ，而使用可供选择的pcsa - b768s isdn装置时isdn的连接则为768kbps 。 - 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 )
用傅立叶级数展开数值逼近的方法进行了高隔离度平顶通带频响全光纤奇偶交错滤波器的优化设计，提出了隔离度大于45db通带平坦滤波器的制作方案。 - 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 .对全光纤反射式奇偶交错滤波器进行了理论分析和数值模拟，发现当两个耦合器的分光比均为15时产生了平顶高隔离度的通带频响特性，做了相关实验，结果与理论分析基本符合。
