Hanning Window

C/C++ Equivalent: NISCOPE_VAL_HANNING_WINDOW

The Hanning window is useful for analyzing transients longer than the time duration of the window, and also for general-purpose applications. A Hanning window is applied to the waveform using the following equation:

y[i] = 0.5 × waveform[i] × [1 – cos(w)]

where w = (21378)i/n and n = waveform size.

1378

Note   Hanning and Hamming windows are somewhat similar. However, in the time domain, the Hamming window does not get as close to zero near the edges as does the Hanning window.
