BPSK_modelation

改变图像的灰度级数，通过输入的数值确定灰度级(change degree of gray )

一种高增益的交错boost变换器，增益可以高达10左右，是一种高效率高增益第成本的变换器。(hige_step boost)

要求：从x(t)=sin(2*pi*5*t)+sin(2*pi*200*t)+sin(2*pi*50*t)信号中滤出频率为5Hz的信号(Requirements: from x (t) = sin (2* pi* 5* t)+ sin (2* pi* 200* t)+ sin (2* pi* 50* t) signal to filter out the signal frequency of 5Hz)

用来生成分形山的matlab程序，直接运行既是用中点法，迭代生成分形山，非常好用(Health ingredients to the matlab procedure Katayama, both directly run by the mid-point method, iterative Katayama Health ingredients, very easy to use)

说明：  JPDA航迹关联算法，Matlab代码，方便初学者学习(JPDA track association algorithm, matlab code, easy for beginners to learn)

matlab program describes bit selection

用牛顿-雅可比迭代法求非线性方程组的一个根(Newton- Jacobi iterative method of nonlinear equations of a root . )

地震数字处理的基本程序，其中包括滤波褶积，fft，dft，自相关互相关，以及偏移等，对地质学人员比较有用(Digital processing seismic basic procedures, including convolution filter, fft, dft, autocorrelation cross correlation, and offset, etc., more useful for people geology)
