chip_histogram_features
特征提取是模式识别中最重要的一个部分,这里提供的matlab代码计算一些基本的话音特征,而且,提供了一个简单的基于直方图的特征分类方法的实现。基本的特征包括:特征统计、Energy Entropy Standard Deviation (std)、均值信息熵、过零率检测、频谱衰减等等六个特征(Pattern recognition feature extraction is the most important part, here' s matlab code to compute some basic voice features, but also provides a simple classification method based on histogram characteristics of the implementation. Basic features include: Features and Statistics, Energy Entropy Standard Deviation (std), mean entropy, the zero-rate detection, attenuation, and so the six characteristics of the spectrum)

lms-50Hz
采集到的50Hz电源信号送至信号处理器作为参考信号,该参考信号在信号处理器中需经HILBERT变换变成两路正交正余弦信号X1、X2,然后采用自适应滤波器算法滤掉有用信号中的50Hz信号。(Collected 50Hz power signal to the signal processor as a reference signal, the reference signal in the signal processor requires HILBERT transform into two orthogonal cosine signal is X1, X2, and then filter out the use of adaptive filter algorithm useful signal in the 50Hz signal.)
