matlab程序，可实现脉冲编码调制，模拟信号的数字传输：抽样、量化、编码-matlab program to achieve pulse code modulation, digital transmission of analog signals: sampling, quantization, coding

构成不同频率的调制信号，从先验概率中采样，计算权重，代码里有很完整的注释和解释，包括AHP，因子分析，回归分析，聚类分析，毕业设计有用，在MATLAB中求图像纹理特征，用于时频分析算法。- Constituting the modulated signals of different frequencies, Sampling a priori probability, calculate the weight, Code, there are very complete notes and
