At its core, Fourier analysis is a mathematical technique that breaks down a signal into its component frequencies. Fourier coefficients represent the amplitude and phase of these frequencies, allowing us to analyze and reconstruct the original signal. This process is based on the Fourier transform, which converts a time-domain signal into a frequency-domain representation. The resulting coefficients provide valuable insights into the signal's structure and behavior.
