因此，它在带外衰减与带内幅度特性和带内群时延特性之间有了一个较好的折中。
Therefore, there is a perfect compromise between attenuation in stopband and group delay or loss variation in passband.
此软件能根据一定的技术指标要求(如带宽、带外衰减等)，优化出双工器最佳参数。
According to the designing demands, such as bandwidth, stop-band attenuation, the optimization software can optimize the diplexers.
文章列举了几组滤波器的实测结果，其中一组在不加任何特别措施的情况下，相对带宽作到了27％，另有一组具有明显的带外衰减极点。
Some experimental results for the filters are given, one has bandwidth of 27% without special measure employed, and another has two evident attenuation poles on either side of the passband.
例如，总是需要的过滤器，以对带外的信号鉴别和衰减下来，以非常低的水平，同时保持全功率在感兴趣的频带。
For example, filters are always needed to discriminate against out-of-band signals and attenuate them down to very low levels while preserving full power in the bands of interest.
