What Does DWT Stand For?

DWT stands for Discrete Wavelet Transform

DWT, or Discrete Wavelet Transform, is a mathematical technique used for signal processing and data analysis that transforms a signal into its constituent wavelets. Unlike traditional Fourier transforms, DWT provides both frequency and time information, enabling the analysis of non-stationary signals. It decomposes a signal into different frequency components at various resolution levels, allowing for effective data compression, feature extraction, and noise reduction in applications such as image processing, audio compression, and various engineering fields.
