Continuous Wavelet Transform (CWT)

The Continuous Wavelet Transform (CWT) is a mathematical tool that analyzes a signal by breaking it down into simpler, wave-like components at different scales and positions. Unlike traditional methods that focus only on frequency or time separately, CWT provides a detailed view of how the signal's frequencies change over time. This allows for detecting localized features such as patterns, edges, or anomalies within the data. Essentially, CWT helps us understand the signal’s structure more precisely, making it useful in fields like signal processing, audio analysis, and data examination.
