Phase-and-Frequency-Detector
- 针对锁频锁相器( Phase and Frequency Detector, PFD) 应用于低信噪比、大频偏的条件, 通过理论分析和仿真验证阐述了窗口类型对系统频偏捕获速度、范围、噪声门限及相位噪声抖动的影响机理. 推导出等效相位噪声功率谱密度的表达式. 证明了大窗口具有更低的噪声门限和更小的稳态相位抖动, 但捕获速度较慢. 为了提高捕获速度, 对鉴相器输出值取极性运算得到改进的PFD 算法. 新算法不仅能增加鉴相增益提高捕获速度 还可以减少等效噪声功率谱密度降低相位抖动 同时新算法不需要乘法

Design-of-Smart-Home-Security-System
- GPRS通信技术实现了多方式遥控设防撤防,解决了主控制器操作 的实时记录问题,为事后分清责任提供了技术保障。现场调试结果表明,系统操作简便灵活,有效地实现了对室内环境信 息(如温度、湿度)的实时监控、险情检测(如火警、被盗、可燃气体泄漏及水泄漏)、多方式遥控设防撤防、远程监控和报警 以及操作数据实时记录等功能,提高了家庭安防报警的可靠性。 -GPRS communication technology to achieve a multi-way remote maximum se
Multi_Gigabit_transceiver
- A Multi-Gigabit Transceiver (MGT) is a SerDes capable of operating at serial bit rates above 1 Gigabit/second. MGTs are used increasingly for data communications because they can run over longer distances, use fewer wires, and thus have lower costs t
