Suppose we need to compute numerically the FT of a stable signal s(t). In practice only a finite vector of samples is available, $$s = \left( {{s_0},...,{s_{N - 1}}} \right)$$ where s n = s(nΔ). The Fourier sum of this vector evaluated at pulsations ω k = 2kπ/N is the discrete Fourier transform (DFT).
