说明: 环路滤波器是通信信号调制解调中最重要的一个部分,环路滤波器设计的好坏将直接影响到接收机的性能指标,二阶锁频辅助三阶锁相环路滤波器可以稳定跟踪具有加加速度的信号源,是现代通信中非常实用的技术,本文中详细编写了单载波信号产生模块、信道噪声模块、数字正交下变频模块、鉴频鉴相模块、环路滤波器模块,并包含了完整的testbench模块,对于初学者非常有用。(Loop filter is the most important part of communication signal modulation and demodulation. The design of loop filter will directly affect the performance index of receiver. The second-order frequency locking assisted third-order phase-locked loop filter can stably track the signal source with acceleration speed, which is a very practical technology in modern communication. In this paper, the single carrier signal generation module and channel noise are written in detail Sound module, digital orthogonal down conversion module, frequency and phase detection module, loop filter module, and contains a complete testbench module, which is very useful for beginners.)

CSS配合jquery制作完美漂亮的时钟,貌似在IE8下时钟不能获取时间啊!支持ie9、chrome、safari、firefox、opera (Chrome显示效果最佳,IE9下时钟无法工作)日历和骰子是原创,CSS3时钟并非原创但经过改良支持opera。数字日历的兼容性不错,圆形时钟就差点了,也希望一起交流,共同改进。(CSS with the jquery make perfect beautiful clock, seemingly in IE8 under the clock can not get the time ah! Support ie9, chrome, safari, firefox, opera (Chrome show the best results, the clock does not work under IE9) calendar and dice is original, CSS3 clock is not original but after improved support opera. Digital calendar compatibility is good, almost round the clock on, and also hope together, and work together to improve.)

8085汇编实现计算器
使用 7 赛格 LED 显示屏车载 (地址和数据字段) 来显示小时: 分钟: 秒的小数。这将意味着你有在董事会上运行一个实时时钟。
(为激励标记!!) 还提供以下附加功能:
(a) 一个计时器设施 (提供启动和停止按钮),找到一个事件所需的时间。
(b) 一个报警设施 (设置和重置警报)。我们可以有多个闹钟吗?
我们可以在哪里显示的短 (神秘) 消息提醒吗?
(d) 在哪里小时的范围从 0-24 而不是 0-12 的铁路时间格式显示时间。
