HarmonicAmplitudeOfTheWaveformSynthesis
- 谐波幅度对波形合成的影响 一个幅度为E，脉冲宽度为τ，重复周期为T的矩形脉冲信号，实验内容为用前5项谐波近似合成一方波。先画出基波分量；然后将三次谐波加到基波上，并画出结果；再将一次、三次、五次、七次和九次谐波加在一起；将上述波形分别画在一幅图中，可以看出它们逼近方波的过程。注意“吉布斯现象”。周期信号傅里叶级数在信号的连续点收敛于该信号，在不连续点收敛于信号左右极限的平均值。如果我们用周期信号傅里叶级数的部分和来近似周期信号，在不连续点附近将会出现起伏和超量。在实际中，如果应用这种近似，就
Wavelet-Analysis
- 小波分析是建立在泛函分析、调和分析、数值分析、逼近论和傅里叶分析等的基础上发展起来的新的时频分析方法。与经典的傅里叶分析相比较，小波变换是空间(时间)和频率的局部变换，因而能有效地从信号中提取信息，因此小波分析有着许多显著的优点。小波变换是空间(时间)和频率的局部变换，因而能有效地从信号中提取信息。通过伸缩和平移等运算功能可对函数或信号进行多尺度的细化分析，解决了Fourier变换不能解决的许多困难问题。 小波分析是时间—尺度分析和多分辨分析的一种新技术，它在信号分析、语音合成、图像识别、计
