基于DSP builder搭建的DDS模块，可以用在数字下变频中的NCO等-Based on DSP builder to build the DDS module can be used in digital down-conversion of the NCO, etc.

本程序可以在quartusII软件仿真下生成m序列和NCO数字振荡发生器，可以后续按个人要求实现通信加密，或传输信号。-This program can generate quartusII software simulation m sequence and NCO digital oscillation generator, you can follow-up according to their individual requirements for communication encry

一個有關於數值控制震盪器(NCO)的檔案,用Matlab的Simulink開啟即可-.-a shaker on the numerical control (NCO) files, Matlab Simulink can be opened.
