WebDec 9, 2024 · where x is the input sequence, X is the DFT, and n is the number of samples in both the discrete-time and the discrete-frequency domains. Direct implementation of the DFT, as shown in equation 2, requires approximately n 2 complex operations. However, computationally efficient algorithms can require as little as n log2(n) operations.These … WebThe DFT algorithm is an N 2 algorithm, so computation time goes up rapidly with the number of points. The DFT sums a set of cosine and sine functions scaled by the points in the data sample. I've tried to show this in the graphs below. These graphs have 17 data points (e.g., a 17-point DFT). The points are generated from the function sin(x).
