Formula for Hamming Window?

W_n is defined by the Hamming window, W n = 0.54 + 0.46 cos ( n π N ) . . 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.

What is the Hamming window function?

The Hamming and Hann window functions both have a sinusoidal shape. Both windows result in a wide peak but low side lobes. However, the Hann window touches zero at both ends eliminating all discontinuity. The Hamming window doesn't quite reach zero and thus still has a slight discontinuity in the signal.

How do you measure Hamming windows?

The following equation generates the coefficients of a Hamming window: w ( n ) = 0.54 − 0.46 cos ( 2 π n N ) , 0 ≤ n ≤ N . The window length L = N + 1.
