Fourier transform methods

The Fourier transform is a mathematical technique that breaks down complex signals into simpler parts. Think of it as a tool that takes a sound, image, or any data set and converts it from its original form into a representation that shows the different frequencies or components it contains. This helps us analyze patterns, identify features, and process information more effectively. For instance, in music, it allows us to separate different notes, while in image processing, it can enhance or filter specific details. Essentially, it reveals the underlying structure of data in a more comprehensible way.
