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.)

关于图形旋转的C语言原代码，对C语言初学者有很大帮助。-Graphics rotation on C language source code for C language has a lot to help beginners.

基于多线程的VC++文件下载示例，程序界面暂且没有美化，可多线程同时执行多个下载任务，像很多有名的FTP软件都具备此功能，因此上传和下载程序都相当快，做FTP软件的朋友可借鉴下思路。

MATLAB的FPGA数字信号处理程序 类似于DSP的C语言 简称SG，大家指教！！ -MATLAB FPGA digital signal processing DSP similar to the C language acronym SG, we know! !

VC++以简单的圆形百分比图表显示内存的使用比率，图表让数据的展现一目了然，不过本程序若电脑配置较高，特别是硬盘或内存容量较大时，圆饼图有失效了，我这里的内存是8G，好像程序获取不到这么大的内存，导致数据错误，圆饼图也失效了，还有修复的必要，时间关系，先把源码与大家分享吧，运行效果如下图所示，失效了。
