Método de Fourier

The Método de Fourier, or Fourier Method, is a technique used to analyze complex signals or functions by breaking them down into simpler, repeating components called sine and cosine waves. Think of it as taking a complicated sound or pattern and expressing it as a combination of pure tones. This decomposition makes it easier to study, process, or analyze signals—like filtering noise from audio or understanding different frequencies in a signal. Essentially, Fourier's method transforms complex data into a sum of simple waves, revealing underlying patterns and frequencies.
