本程序用matlab编写,主要是为解决IEEE40节点电力负荷分配问题而想的一种算法。我把该算法命名为水桶法,是受一桶水的高度总与这个桶的最短一块木板齐平的原理,算法每次迭代把功率分配给需要最小消耗的机组上。(This program with matlab, main is to solve the IEEE40 node power load distribution and think of an algorithm. I put the algorithm named bucket method, by a bucket of water is the height of the barrels of the shortest total and a board at the principle, each iteration algorithm the power allocation to the minimum consumption on the unit needs. )

选取windows系统自带的ding.wav信号作为分析对象,在Matlab软件平台下,利用函数wavread对音频信号进行采样,记住采样频率和采样点数,听一下原始声音sound(y, fs, bits)。
(2)音频信号的频谱分析,先画出音频信号的时域波形;然后对音频号进行快速傅里叶变换fft(y,N),N取32768,画出信号的频谱特性,加深对频谱特性的理解。
(3)根据频谱,反演时域特性,画出时域波形。寻找幅值最大的两个频率,此频率除以fft点数在乘以采样频率就是信号的主频,即可合成信号的时域图形,听一下声音。
(4)对原音频信号进行1024点的分段付立业分析meshgrid
(5)根据主要频线合成音频,并画出时域图形,试听合成效果。
(6)采用线性插值(linspace)和傅立业反变换(fliplr, ifft)分别合成音频,并画出时域图形,试听效果。
