      The Fourier transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. In essence, it decomposes a signal into its constituent frequencies, allowing for the analysis and manipulation of individual frequency components. This is achieved by representing the input signal as a sum of sinusoids with different amplitudes and frequencies. The resulting output is a frequency spectrum, which displays the distribution of energy across different frequencies.
