可产生矩形脉冲和正弦信号，矩形脉冲的脉宽可以改变，正弦信号则可以改变频率和时宽-Can produce rectangular pulse and sinusoidal signal, the rectangular pulse width can be changed, sinusoidal signal can be changed when the frequency and width

This file is about a rectangular-pulse system. This source file will be very helpful for an engineer who study in IT.

包括面积、周长、矩形度、伸长度，采用的是脉冲对消法，基于分段非线性权重值的Pso算法。- Including the area, perimeter, rectangular, elongation, It uses a pulse of consumer law, Based on piecewise nonlinear weight value Pso algorithm.

重点分析信号在时域中为矩形脉冲具有sinc函数的特点，以此为基础，探讨小波和傅里叶之间的变换关系，既是小波与傅里叶分析基础,也是图像处理方面的资料-Key analytical signal in the time domain characteristic of a rectangular pulse having a sinc function as a basis to explore the relationship between wavelet and Fourier transfo
