verilog HDL语言程序，运行后实验板四位数码管依次加法计数，从1到9999计数，超过后即溢出，重新从1开始 计数

基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和 VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要 求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种 方法都能有效地实现DDS中波形存储表的设计。 (DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)

基于xilinx公司的Basys2开发板开发的FPGA数字钟，实现了时钟、闹钟和秒表等功能,同时包含了测试程序。使用Verilog语言编写，开发软件为Xilinx ISE Design Suite 13.4。

基于ad7470，ad5331的数模转换和模数转换的采集系统，已通过modelsim和quartus验证，输入0到2.5v的正弦波波形，转换输出通过采集卡的波形基本类似。

把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。 (The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)
