按键在数字电路设计中经常用到。按键的弹跳现象是数字系统设计中存在的客观问题。按键是机械触点，当接触点断开或闭合时会产生抖动。为使每一次按键只做一次响应，就必须去...

matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), 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 frequency (receive data), Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the lock data the rising and falling edge; top-level document is PLL.GDF
