程序为常规AM，DSB，SSB调幅信号的调制与解调的MATLAB程序，其中单边带调制用两种方法进行调制：一种为频谱直接变换，另一种为希尔伯特变换实现(MATLAB for norm AM,DSB and SSB modulation and demodulation,besides,modulation for SSB,has tow ways:frequency spectrum transform and hilbert transform)

he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of intervals [ak,bk] that is guaranteed to converge to a solution to f(x) = 0.

说明：  这个小程序主要介绍了快速傅里叶变化的MATLAB算法的实现功能。(This small program introduces a fast Fourier transform of the function of MATLAB algorithm implementation.)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

改程序勇于特征降维。使用PCA的方法降低特征维度(Courage to change the feature dimension reduction program. Use PCA method to reduce the dimension feature)

The program computes the solution to a Laplace problem by the boundary element method.
