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

one, producer
1、 生产者―消费者问题是一种同步问题的抽象描述。
2、 计算机系统中的每个进程都可以消费或生产某类资源。当系统中某一进程使用某一资源时，可以看作是消耗，且该进程称为消费者。
3、 而当某个进程释放资源时，则它就相当一个生产者
-one, producer-consumer problem is a problem of synchronization of the abstract description. 2, the computer systems of each process can consumption or production of certain resources. When a process system using a resource, can be seen as expendable, and the process known as consumers. 3, and when a process to release resources, then it is a producer

信号灯受一个启动开关控制，当启动开关接通时，系统开始正常工作，且先南北红灯亮，东西绿灯亮；当启动开关断开时，所有信号灯熄灭；南北绿灯和东西绿灯不能同时亮，如果同时亮则应报警后关闭信号灯系统。-To start signal by a switch control, when the start switch connected to the system started to work, and the first north-south red light, green things when the start switch off all lights extinguished north-south and east-west green light green light can not be at the same time, if At the same time, bright lights should be shut down after alarm system.
