代码说明:

  Matlab编程实现FFT变换及频谱分析的程序代码(适合初学者加强理解)。(1)用Matlab产生正弦波,矩形波,以及白噪声信号,并显示各自时域波形图;(2)进行FFT变换,显示各自频谱图,其中采样率,频率、数据长度自选;(3)做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱;(4)用IFFT傅立叶反变换恢复信号,并显示恢复的正弦信号时域波形图。(Matlab codes for FFT Understanding which contains sine wave,rectangular wave and the reletaed frequency spectrum figure about MSE,Log,IFFT and so on.)

    n mathematics, a wavelet series is a representation of a square-integrable (real- or complex-valued) function by a certain orthonormal series generated by a wavelet. Nowadays, wavelet transformation is one of the most popular candidates of the time-frequency-transformations. This article provides a formal, mathematical definition of an orthonormal wavelet and of the integral wavelet transform
