Sullivan关于FTDT经典文章的MATLAB翻译，例子的源程序。(Sullivan classic article on the FTDT translation of MATLAB, examples of the source.)

说明：  此算法为最小二乘辅助变量法。uy2为含噪声数据，n=2,噪声模型n=2。左为输出数据，右为输入数据。k=2,3,4,5等等(Least-squares algorithm for the auxiliary variables. uy2 for data containing noise, n = 2, the noise model n = 2. Output data for the left and right for the input data. k = 2,3,4,5, etc.)

付里叶变换的频移特性；付里叶变换的时域卷积特性(Fourier transform of the frequency shift characteristics the Fourier transform of time domain convolution properties)

需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序，或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换，甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)

说明：  利用Matlab编写求取4级移位寄存器的M序列 设初始序列为:1 1 1 1 通过一个四级的移位寄存器,其中在第三级有负反馈(一个模二加法),即将序列的第三位和第四位相加(如序列1 1 1 1经移位寄存器第一次移位后为0 1 1 1)的值再赋到第一位. 序列的周期为16.(The use of Matlab to prepare to strike four of the M shift register sequence based initial sequence as follows: 1 1 1 1 4 through a shift register, which in the third grade there is negative feedback (one-mode two adder), the upcoming series third and fourth combined (such as the sequence 1 1 1 1 by the shift register after the first shift for the 0 1 1 1) the value given to the first again. The cycle sequence was 16.)
