WebWn is defined by the Hamming window, . The sampling interval used in all the tests was chosen to be 0.1984 s. The natural surge period for all the experiments ranges from 8 s to 24 s and the wave period varies between 0.5 s to 2 s. A filter half span of N = 30 with a cut-off period of 4 s was therefore employed. WebMay 2, 2024 · Which means the FIR filter length would be M=n+1.
