FrequencyHoppingTechnology
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)

vc-cpp
c语言实现，能够输入和查询客户存款取款记录。在客户文件中，每个客户是一条记录，包括编号、客户姓名、支取密码、客户地址、客户电话、账户总金额；在存取款文件中，每次存取款是一条记录，包括编号、日期、类别、存取数目、经办人。类别分为取款和存款两种。本系统能够输入客户存款或取款记录；根据客户姓名查询存款和取款记录。(c language, be able to enter and query the records of customer deposit withdrawals. , Each customer is a record in the customer file, including the number, customer name, withdraw the password, the customer address, customer phone account the total amount in the deposit file, each deposit is a record, including the number, date, category, access the number of managers. The categories are divided into two kinds of withdrawals and deposits. The system can enter the customer deposits or withdrawals records their deposits and withdrawals recorded according to the customer' s name.)
