(20) For each example, we plot the DFT as a function of ( and ) and as a function of frequency , DFT: Properties Linearity Circular shift of a sequence: if X(k) = DFT{x(n)}then X(k)e−j2πkm N = DFT{x((n−m)modN)} Also if x(n) = DFT−1{X(k)}then x((n−m)modN) = DFT−1{X(k)e−j2πkm N} where the operation modN denotes the periodic extension ex(n) of the signal x(n): xe(n) = x(nmodN). EE 524, Fall 2004, # 5 17 In this video, it demonstrates how to compute the Discrete Fourier Transform (DFT) for the given Discrete time sequence x(n)={0,1,2,3} We know that DFT of sequence x(n) is denoted by X(K). Now, if x(n) and X(K) are complex valued sequence, then it can be represented as under $x(n) = x_R(n)+jx_1(n),0\leq n\leq N-1$ 7.1 The DFT The Discrete Fourier Transform (DFT) is the equivalent of the continuous Fourier Transform for signals known only at instants separated by sample times (i.e. a finite sequence of data). Let be the continuous signal which is the source of the data. Let samples be denoted . Example.

Therefore, the Discrete Fourier Transform of the sequence x [ n] can be defined as: X [ k] = ∑ n = 0 N − 1 x [ n] e − j 2 π k n / N ( k = 0: N − 1) The equation can be written in matrix form: where W = e − j 2 π / N and W = W 2 N = 1 . Quite a few people use W N for W. So, our final DFT equation can be defined like this:
