WebThe DFT overall is a function that maps a vector of n complex numbers to another vector of n complex numbers. Using 0-based indexing, let x ( t) denote the t th element of the input vector and let X ( k) denote the k th element of the output vector. Then the basic DFT is given by the following formula: X ( k) = ∑ t = 0 n − 1 x ( t) e − 2 ...
