增强的音频工程

QAM调制，基于FPGA的实现，包含有乘法器模块、升降余弦滤波器模块、QAM序列生成模块(QAM modulator,the implementation based on FPGA,include MUL、FIRCOS and QAM generate)

数字钟电路的实现，可以24小时计时，可调整时间！(Digital clock circuit implementation, a 24-hour timer, adjustable time!)

16QAM调制解调程序画出时域波形、 正交分量、同相分量波形，眼图，散点图等(16QAM modulation and demodulation process to draw time-domain waveform, quadrature components, in-phase component waveforms, eye diagrams, scatter plots, etc.)

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

VHDL电梯控制器程序设计与仿真，内含原理图和VHDL源码，有助于学习VHFL(VHDL u7535 u68AF u63A7 u5236 u5668 u7A0B u5E8F u8BBE u8BA1 u4E0E u4EFF u771F)

在Altera的FPGA开发板上运行第一个FPGA程序，以后我还会陆续发布这方面的代码-In Altera

LOW pass FIR filter for multirate processing
