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。

This paper presents a new and efficient approach for capacitor placement in
radial distribution systems (RDS) that determine the optimal locations and size of
capacitor with an objective of improving the voltage profile and reduction of power loss.
The solution methodology has two parts: in part one the loss sensitivity factors (LSF) are
used to select the candidate locations for the capacitor placement and in part two a new
algorithm that employs Dijkstra Algorithm (DA) is used to estimate the optimal size of
capacitors at the optimal buses determined in part one. The main advantage of the
proposed method is that it does not require any external control parameters. The other
advantage is that it handles the objective function and the constraints separately. The
proposed method is applied to 33 & 69 RDS. The solutions obtained by the proposed
method are compared with other methods. The proposed method has outperformed the
other methods in terms of the quality of solution.
