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)

常见的SCPI错误, 在使用支持SCPI指令集的可编程仪器时特别有用(COMMON ERROR OF SCPI,It s useful for program instrument which support scpi)

说明：  银行排队系统的VHDL程序实现，可以实现排队顾客自动取号，查看前面排队人数，银行服务柜台号等。(Bank queuing system VHDL program can be achieved automatically check its customers lined up to view the queue in front of the number of its banking services, such as counters.)

基于SIMULINK对开关磁阻电机做的仿真工作，内容非常详细。(SIMULINK simulation of switched reluctance motor do the work, the content is very detailed.)

用MFC做的一个学生信息管理系统，有增加、删除、排序、筛选功能，系统通过ODBC方式连接数据库。 由于文库不支持RAR，故需要完整的程序以及数据库可以联系俺，希望对大家有帮助。 (To do with the MFC, a student information management system, increase, delete, sort, filter functions, the system through ODBC to connect to the database. The library does not support RAR, I therefore need to complete the program and database can be contacted, we hope to help.)
