Fourier transformation

Fourier transformation is a mathematical process that converts a complex signal, such as sound or light waves, into its individual frequency components. Imagine breaking a song down into its different musical notes. This transformation allows us to analyze and understand the signal's structure by identifying the various frequencies and their amplitudes. It's widely used in engineering, physics, and data analysis to simplify problems, filter signals, or visualize information more effectively. Essentially, it reveals the hidden patterns within complex data, helping us see the underlying details that aren't immediately obvious.
