Additionally, the one or more filters selected by the signal filtering device may include different types of wavelet filters. The term wavelet (Wavelet), as the name suggests, "wavelet" is a small waveform. The so-called "small" means that it has attenuation; the term "wave" means its volatility, and its amplitude is positive and negative. Compared with the Fourier transform, the wavelet transform is a localized analysis of time (space) frequency. It gradually refines the signal (function) on multiple scales through stretching and translation operations, and finally achieves time subdivision at high frequencies and frequency subdivision at low frequencies. , can automatically adapt to the requirements of time-frequency signal analysis, so that it can focus on any details of the signal, solve the difficult problem of Fourier transform, and become a major breakthrough in scientific methods since Fourier transform.

The application of wavelet analysis is closely combined with the theoretical research of wavelet analysis. He has made remarkable achievements in the field of science and technology information industry. Electronic information technology is an important field among the six high-tech fields, and its important aspect is image and signal processing. Today, signal processing has become an important part of contemporary scientific and technological work. The purpose of signal processing is: accurate analysis, diagnosis, code compression and quantization, fast transmission or storage, and accurate reconstruction (or recovery). From a mathematical point of view, signal and image processing can be regarded as signal processing (image can be regarded as a two-dimensional signal), and many applications of wavelet analysis can be attributed to signal processing problems. For signals whose properties are stationary over time, the ideal tool for processing remains Fourier analysis. But most of the signals in practical applications are unsteady, and the tool that is especially suitable for unsteady signals is wavelet analysis.
