电力系统潮流计算 运用MATLAB软件来实现这一功能(Power Flow using MATLAB software to achieve this functionality)

线性预测法是语音处理中的核心技术，它在语音识别、合成、编码、说话人识别等方面都得到了成功应用。有的专家认为，进20年中语音处理技术的飞速发展与以线性预测为中心的信号处理技术是分不开的。简单来说，就是：一个语音的抽样能用过去若干语音抽样的线性组合来逼近。 (Linear prediction is the core voice processing technology, which in speech recognition, synthesis, coding, speaker recognition and so on have been successfully applied. Some experts believe that 20 years into the rapid development of voice processing technology and to forecast as the center of linear signal processing technology are inseparable. To put it simply, is: Can a voice sample voice over the past number of linear combinations to approximate the sample.)
