+The **Discrete Fourier Transform** (DFT) is a mathematical tool that reveals the hidden frequencies within a finite sequence of data points. It decomposes a signal into its constituent pure tones, transforming it from the [Time Domain](/wiki/time_domain) into the [Frequency Domain](/wiki/frequency_domain) for analysis.
