网上分享的一段100例子，适合FPGA学习的初学者。内部还有一些经典实用技巧。                                                                        

利用matlab设计了一个切比雪夫滤波器，并且对滤波器性能进行了仿真分析。(Using the matlab design a chebyshev filter, and has carried on the simulation analysis on filter performance. )

本源码为Nios II的开发示例,主要演示基于Nios II的uCOS的移植。开发环境QuartusII。 本示例十分经典，对基于SOPC开发的FPGA初学者有很大帮助。-The source code for the Nios II development of examples, mainly based on the Nios II shows the uCOS transplant. Development environment QuartusII. This example is very classic, FPGA-based SOPC development of great help for beginners.

说明：  发送两个频段的脉冲 个数和频率均可调 发送两个频段的脉冲 个数和频率均可调(pluse and adjust the width of pluse pluse and adjust the width of pluse )
