在数字通信中，通常直接从接收到的数字信号中提取位同步信号，这种直接法按其提取同步信号的方式，大致可分为滤波法和锁相法。锁相法是指利用锁相环来提取位同步信号的方法，本设计方案就是基于锁相环的位同步提取方法，能够比较快速地提取位同步时钟，并且设计简单，方便修改参数。采用Quartus II设计软件对系统进行了仿真试验，并用Altera的Cyclone II系列FPGA芯片Ep2c5予以实现。(In digital communication, usually from receiving directly in digital signal extracted a synchronized signal, the direct method according to the extraction synchronized signal way, can be roughly divided into filtering method and phase lock method. Phase lock method is using of phase locked loop to extract a synchronized signal method, the design scheme is based on phase locked loop of a synchronous extraction method and can be quickly extract a synchronous clock, and design simple, convenient modification parameter. The Quartus II design software of the system, and the simulation test Altera Cyclone II FPGA chip to achieve Ep2c5 series.)

基于FPGA的交通控制器
设计一个由一条主干道和一条支干道的汇合点形成的十字交叉路口的交通灯控制器： 1) 主、支干道各设有3个方向的绿、黄、红指示灯（左转、直行和右转），每个行驶方向均配有时间显示数码管；2) 主干道处于常允许通行状态，而支干道有车来才允许通行（由外部信号通知）。3) 当主、支道均有车时，两者交替允许通行，主干道每次放行90s，支干道每次放行60s，在每次由亮绿灯变成亮红灯的转换过程中，要亮5s黄灯作为过渡，并进行减计时显示。
