在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案-The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program

程序员对代码所做的为了满足短期利益代码改动，或再没有完全清楚增个架构下的改动，都很容易是代码失去它的清晰结构，偏离需求或设计。而这些改动的积累很容易使代码偏离它原先设计的初衷而变得不可立即和无法维护。
Refactoring则帮助重新组织代码，重新清晰的体现结构和进一步改进设计。
-programmers to code done in order to meet short-term interest code changes or not entirely clear by a framework of the changes, it is easy to lose its code is a clear structure, depart from the demand or design. And the accumulation of these changes are easier to make code from its original intention of the original design has become an immediate and unable to preserve. Refactoring is helping to reorganize code, re- clearly reflected structure and further improve the design.
