Purpose of Fourier Transform as well as DFT – Discrete Fourier Transform is to transform input signal (analog or digital) to sum of sine and cosine coefficients.DFT i.e. Discrete Fourier Transform is Fourier Transform adjusted to digital (sampled signal). In case of digital input signal, analog integral is replaced by finite sum. This application calculate sin and cosine DFT coefficients from an signal array and vice versa.
