Wavelets are small waves typically used in signal processing, digital image processing, and communications. There are several synonyms for wavelets including small waves, ripples, undulations, oscillations, pulsations, vibrations, and crests. Each of these words describes a small movement or disturbance in a medium that creates a wave-like pattern. Wavelets are often used in data compression and analysis, as well as in scientific research and engineering applications. Some other related terms for wavelets include Fourier transforms, signal decomposition, and spectral analysis. Understanding the properties and characteristics of wavelets is important in many fields, including physics, engineering, and computer science.
