说明：  使用FFT分析方波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(Square-wave signal using the FFT spectrum analysis to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)

用粒子群优化算法（PSO）求peaks函数的极值(Particle swarm optimization (PSO) seeking the extreme peaks function)

IMCIRCLE Generates a circle inside a rectangle

这个方法有两个好处。 （ a ）虽然只是一个半径差逼近，很容易找到最高在一个小蓄电池，因为通过降低 隐平滑做的蓄电池。（ b ）在同一时间处理时间搜索减少 (Pattern Recognition and Image Procesing Group. The size of the accumulator is varied as hierarchical voting is performed. This has two advantages. [a] While the radius is only a poor approximation, it is easier to find the maximum in a small accumulator and because by means of the downsampling implicit smoothing is done to the accumulator. [b] At the same time processing time for the search is reduced.)

说明：  快速傅里叶变换的子程序，直接在主函数中调用即可直接绘制信号的频谱图。(The subroutine of the fast Fourier transform can directly draw the spectrum of the signal by calling it directly in the main function.)
