此为中值滤波原程序,通过matlab调用可实现滤波(this filter for the original procedure for the adoption of Matlab can be called Filter)

变频调速系统仿真搭建模型 由于观测仿真波形 记录以及分析实验结果(Variable speed control system simulation build the observation model simulation and analysis of experimental results wave record)

经典功率谱估计方法——直接法和间接法,以及改进的经典功率谱估计方法-Welch法(Classic power spectral estimation methods- direct and indirect methods, as well as improvements to the classic power-Welch method of spectral estimation method)

说明：  用matlab实现K均值聚类算法，里面有详细的英文备注和举例，可以看明白(Achieved using K means clustering algorithm matlab)

脉冲编码调制是数字通信的编码方式之一。主要过程是将话音、图像等模拟信号每隔一定时间进行取样，使其离散化，同时将抽样值按分层单位四舍五入取整量化，同时将抽样值按一组二进制码来表示抽样脉冲的幅值。(PCM pulse code modulation is one of the encoding methods of digital communication. The main process is to voice, image and other analog signal at a certain time for sampling, the discretization, while the sampling values by the hierarchical units four to five homes in rounding quantization, while the sampling value indicates the sample pulse amplitude according to a set of binary code.)
