Fouriertransform
用振幅为0.8的方波进行傅立叶分析,并用分析得到的系数求解当K取不同值时的合成信号( F = FOURIER(f) is the Fourier transform of the sym scalar f with default independent variable x. The default return is a function of w.
This example is useful for the persons who learn sth about signal processing.)

Matlab函数 采集一段浊音和清音语音信号
(1) 使用录音软件或者Matlab函数,分别采集一段浊音和清音语音信号(是你自己说的,如:a,o,s等),采样率为8KHz,量化精度为16比特线性码,存在自己指定的目录下,例如D盘根目录下叫sound的文件夹中,录音文件名为yourfilename_a.wav,yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。
(2) 根据语音信号的短时平稳特性,分析帧长取30ms(或10ms~50ms);
(3) 利用上述基音提取的三种方法(任选两种方法)的编程流程图(图1、图2和图3)编制浊音语音基音提取的matlab程序,上机调试给出相应波形,并根据图形,分析计算出基音周期。所用公式为:
(1.5)
其中 是基音脉冲处所对应的位置, 是抽样频率, 是基音周期。
(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。

Two-tank-water-level-fuzzy-pid
针对双容水箱液位会受到外界环境干扰和内部摄动的影响,导致水箱液位出现较大波动等问题,提出将模糊控制技术与PID控制相结合的自适应水箱液位控制方法,设计出自适应模糊PID控制器。(Aiming at the problem that the level of the double-tank is affected by the disturbance of the external environment and the internal perturbation, the water level of the tank is greatly fluctuated. An adaptive tank level control method combining the fuzzy control technology with the PID control is proposed. Adaptive fuzzy PID controller.)
