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 coefficients of a flat top window are computed from the following equation: where 0 ≤ n ≤ L − 1. The coefficient values are: Flat top windows have very low passband ripple (< 0.01 dB) and are used primarily for calibration purposes. Their bandwidth is approximately 2.5 times wider than a Hann window.
