代码说明:

  信号由三个频率分别为0.01,0.1,0.2的正弦信号组成。 (1)作信号的连续小波变换。 (2)自己选择小波基数,对信号进行多尺度分解,将每一个正弦信号分开。 (3)重建原信号。 (Signal from the three frequencies were 0.01,0.1,0.2 sinusoidal signals. (1) continuous wavelet transform for signal. (2) choose the wavelet base, multi-scale decomposition of signals, a sinusoidal signal of each separate. (3) reconstruction of the original signal.)
