设计一个低通滤波系统，任意输入三个频率使输入的信号中留下频率最低的 一个分量。(Designed a low-pass filter system, indiscriminate importation of the three input signal frequency so that left one of the lowest frequency component.)

对要发送的序列进行上变频，上变频到21MHz后进行发送。(change the frequence uop to the one that suit for transmission,which here is 21MHz.)

基于matlab的连续信号的实现，包括常见的抽样函数，矩形，三角等信号(Achieve the matlab continuous signal, including the common sampling function, rectangular, triangular signal)

Brownian motion. A random walk is similar to markov process, however a markov process has no memory, where a random walk uses an initial state. The next step in the walk does not necessarily depend on your current state but will be referenced from your current state, that is to say the random vector is added to your current state. depending on complexity

说明：  该文提出了一种分段弱阈值修正共轭梯度追踪算法，该算法修正了方向追踪算法的方向，提高了压缩感知的重构精度。(This paper presents a weak sub-threshold tracking Conjugate gradient algorithm, which fixes the direction of the direction of tracking algorithms to improve the accuracy of the reconstruction of compressed sensing.)
