数字锁相环设计源程序
- PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 数字锁相技术在通信领域应用非常广泛,本例用VHDL描述了一个锁相环作为参考,源码已经调试过。编译器synplicty.Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上;顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input freque

脉冲记时CPLD
- 工作原理: 脉冲输入,记录30个脉冲的间隔时间(总时间),LED显示出来,牵涉到数码管的轮流点亮,以及LED的码。输入端口一定要用个 74LS14整一下,图上没有。数码管使用共阴数码管。MAXPLUS编译。 测试时将光电门的信号端一块连接到J2口的第三管脚,同时第一管脚为地,应该与光电门的地连接(共地)。 开始测试: 按下按键,应该可以见到LED被点亮,指示可以开始转动转动惯量盘,等遮光片遮挡30次光电门后, LED熄灭,数码管有数字显示,此为时间值,单位为秒,与智
