FT (Fourier Transform)

The Fourier Transform is a mathematical tool that transforms a signal (like sound or an image) from its original form into a representation based on its frequency components. Imagine it as breaking down a complex musical composition into individual notes: the transform identifies and quantifies each frequency in the signal. This is useful in various fields, such as engineering and data analysis, enabling us to analyze, filter, or compress data. In essence, it helps us understand the "ingredients" of a signal, revealing patterns that may not be evident in its time-based form.
