随机噪声生成程序，包括高斯分布、随机分布、泊松分布三种分布，适用于各种信号处理的信号生成添加噪声-Random noise generator, including a Gaussian distribution, random distribution, distribution of three types of Poisson distribution, for a variety of signal processing of adding the noise signal genera

Gaussian white noise generator, There are detailed notes, Is a two hidden layer back propagation neural network.
