This article is mainly about the application of wavelet in spectrum analysis. In signal processing, we usually need to know different frequency components in the signal. We use the frequency bands dividing characteristic of wavelet and FFT to process signals and pick up different frequency components. In processing, we find that there is frequency alias in sub-band reconstruction which is caused by Mallat algorithm. In this article, we offer a solution of this problem.
