- 对录音信号集 中的某一语音,利用BATLAB设计一美尔例谱算法,并实现。 取信号集 中的一个语音信号:“xxxxxx”,将它作为输入的语音信号来为设计一个美尔倒谱算法,在该算法中,主要设计了以下环节: 1.读入一个语音信号;2.对这个信号归一化;3.对归一化的信号进行加窗处理(这里的矩形窗长度必须为257,重帧长64);4.进行预加重处理,即通过一个高通滤波器: ;5进行512点的FFT;6.分别取模平方得到功率谱;7.在设计的mel滤波器组中,我采用了25个带通滤波器;8.将得到的功率
cic
- 在信号处理中,信号发射时,信号通过载波,调制,以电磁波的形式发射出来 在接收端,射频信号通过天线接收,超外差式等方式进行处理,变频到中频 然后通过数字技术对中频信号进行处理,此时的中频信号采样率很高,多达几十兆赫 而要解调出来的信号很小,此时就要经过滤波来得到我们需要的信号 如果直接设计滤波器,阶数会非常庞大,软件,硬件设备都承受不了 因此,一般常用的技术是进行下变频处理,其主要技术就是通过抽取滤波进行下变频 常用的滤波器就是CIC抽取, 希望可以帮助一些坛友解决基本的问

- 以中等纯度的精馏塔为研究对象,考虑到不等分子溢流的影响和非理想的汽液平衡,可以得到塔顶产品轻组分含量Y与回流量L之间的传递函数为: 其中由于现场环境干扰,输出带有测量噪声是(0,1)的正态分布序列,它的方差为ɑ=0.5。由于输出中带有很大的噪声信号,故将数字滤波技术中常见的低通滤波器由于偏差控制,滤掉其中的噪声信号,然后在对其进行PID计算,得到实际的控制量。在该方法在噪声较强的环境下,可以得到较好的控制效果。 控制要求: 1、 采用带低通滤波器的增量式PID将塔顶轻

- 单纯形法,求解线性规划问题的通用方法。单纯形法的基本思想是:先找出一个基本可行解,对它进行鉴别,看是否是最优解;若不是,则按照一定法则转换到另一改进的基本可行解,再鉴别;若仍不是,则再转换,按此重复进行。因基本可行解的个数有限,故经有限次转换必能得出问题的最优解。如果问题无最优解也可用此法判别。 -Simplex method, the general method for the linear programming problem. Simplex method the basic id
