• These two N-point DFTs can be computed efficiently using a single N-point DFT. • Define a complex length-N sequence. • Hence, g[n] The interval at which the DTFT is sampled is the reciprocal of the duration of the input sequence. An inverse DFT is a Fourier series, using the DTFT samples as As the name implies, the Discrete Fourier Transform (DFT) is purely discrete: discrete-time data sets are converted into a discrete-frequency representation. In this way, the linear convolution between two sequences having a different length.

Equation (8) is a closed-form expression for the positive-frequency DFT of a real-valued input cosine sequence. (We could perform the algebraic acrobatics to convert Eq. (8) into a familiar sin (x)/x form, but we need not do that here.) With the original DFT input being exactly integer k cycles of a cosine sequence, to verify Eq.
