数字电子设备上下计数器的实现

使用FPGA完成AGC 自动增益的代码，适合初学者(FPGA to complete the use of AGC automatic gain code, suitable for beginners)

该程序实现最小频移键控信号的调制解调，经测试无误。(The program implements minimum shift keying signal modulation and demodulation, tested and correct.)

该模块已经成功运用在xilinx xc6slx45t，xc6slx75t多个产品中，经过实践证明，采用dna及其加密算法加密是一种成本低廉（无需另外加密芯片）可靠的加密手段。Xilinx Spartan-6 FPGA读取DNA数据并进行比较，产生比较结果信号输出。附带有xilinx DNA.ppt说明及调试注意事项。(The module has been successfully used in xilinx xc6slx45t, multiple xc6slx75t products, proven, and the encryption algorithm uses dna is a low-cost (no additional encryption chip) reliable means of encryption. Xilinx Spartan-6 FPGA reads the data and compare DNA to produce a comparison result signal output. Xilinx DNA.ppt comes with instructions and commissioning notes.)
