返回信息流在介绍小波变换的文献中有下面的一段话:
A wave is an oscillating function of time or space and is periodic. In contrast, wavelets are localized waves. They have their energy concentrated in time or space and are suited to analysis of transient signals. While Fourier Transform and STFT use waves to analyze signals, the Wavelet Transform uses wavelets of finite energy.
不知道上面的话中wave和wavelets的物理意义是什么?请大牛帮忙解释。谢谢
