What is wavelet analysis used for?

The wavelet transform (WT) can be used to analyze signals in time–frequency space and reduce noise, while retaining the important components in the original signals. In the past 20 years, WT has become a very effective tool in signal processing.

Where are wavelets used?

Wavelets are used in the solution of partial differential equa- tions and integral equations. The first use of wavelets was by Haar in 1909. He was interested in finding a basis on a functional space similar to Fourier's basis in frequency space.

What is the main advantage of wavelets?

One of the main advantages of wavelets is that they offer a simultaneous localization in time and frequency domain. The second main advantage of wavelets is that, using fast wavelet transform, it is computationally very fast. Wavelets have the great advantage of being able to separate the fine details in a signal.

Why is wavelet better than FFT?

The key advantage of the Wavelet Transform compared to the Fourier Transform is the ability to extract both local spectral and temporal information.
