代码说明:

  (1) 分别采集一段浊音和清音语音信号(是你自己说的),采样率为8KHZ,量化精度为16比特线性码; (2) 分析帧长取为30ms(或10ms~50ms); (3) 根据语音信号倒谱分析和LPC谱分析的编程流程图(图2.1、图2.2)编制浊音语音信号谱分析的matlab程序,上机调试给出相应波形,并根据图形,观察共振峰情况; (4) 将语音信号换为清音语音,运行程序,与浊音语音的运行结果进行比较,并得出结论。 (5) 在LPC谱分析中,改变阶数p (p分别等于4、8、12、40)时,观察对谱包络的影响,并与信号谱(DFT谱)进行比较。 ( voice signal processing)

  • Fuzzy-PID-dual-mode-control-system
    交流位置伺服系统因其存在参数时变、负载扰动以及电机的非线性等缺点, 很难为其建立准确的模型. 模糊( fuzzy)控制具有无需建立被控对象的数学模型、鲁棒性好等 优点,但稳态精度差. 将模糊控制和PID 控制相结合,设计了Fuzzy-PID 双模控制器. 在论域内 用不同的控制方式分段实现控制,这样就综合了模糊控制和PID 控制的优点,克服了各自的缺 点. 该控制器结构简单、易于实现. 在半闭环交流位置伺服系统上所做的实验表明,采用Fuzzy- PID 双模控制器与采用经典PID 控制器相比,阶跃响应的调整时间减少了33. 7 ,并且无超 调,轨迹跟踪误差减小了47. 2 .(AC servo system because of the presence of parameter variations, load disturbances and non-linear motors and other shortcomings, it is difficult to establish accurate models for fuzzy (fuzzy) control without having to build a mathematical model of controlled object, robustness and good However, steady-state accuracy is poor. fuzzy control and PID control are combined to design a dual-mode Fuzzy-PID controller in the sub-region to achieve control on the different control methods, so that a combination of fuzzy control and PID control advantages to overcome their disadvantages. simply the controller structure, easy to implement. experiments on semi-closed loop AC servo system did show that the Fuzzy-PID controller is compared with the classic dual-mode PID controller, step response The adjustment time is reduced by 33.7 , and no overshoot, tracking error is reduced 47.2 .)

    研究表明,构成K一L变换矩阵的向量也就是ToePhtz矩阵的特征向量。与此同时,离散 余弦变换矩阵逼近于ToePutz矩阵的特征向量矩阵,所以离散余弦变换矩阵与自然图像的 K一L变换矩阵十分相似。经过离散余弦变换后的变换系数块的协方差矩阵Cy非常接近对角 阵,即除了对角线元素以外,其它很多元素都近似为0,并且在左上角集中了主要能量。这 反映了自然图像大部分区域变化不大,亮度突变只占少数,即图像能量以低频成分为主的特 性。通过变换后的量化,舍弃对视觉效果影响较小的次要信息,可达到进一步的压缩效果。 虽然从去相关性能的意义上讲,DCT是一种次于K一L变换的准最佳变换,但是从算法实现的角度来看,DCT则远远优于K一L变换。首先,当图像的分块大小确定后,DCT的变换矩阵也就随之确定了,不随输入信号的统计特性变化而变化 其次,二维DCT能够分解成两次一维DCT,有利于硬件实现。 (Studies have shown that constitute a K L transformation matrix vector is ToePhtz eigenvector of the matrix. At the same time, discrete The cosine transform matrix approximation in ToePutz matrix eigenvector matrix, so the discrete cosine transform matrix and natural images Is very similar to a K L transformation matrix. After discrete cosine transform, the transform coefficient block of Cy is very close to the diagonal of covariance matrix Matrix, namely except diagonal elements, many other elements are approximate to 0, and focused the main energy in the upper left corner. this Reflects the natural images most area changed little, brightness mutations accounted for only a few, the energy is given priority to with low frequency components of image Sex. Through quantitative after transformation, abandoning smaller effect on the visual performance of secondary information, can achieve further compression effect. Although from related to the performance of the sense, DCT is a kind o)
