HammingWindow
represents a Hamming window function of x.
Details

- HammingWindow is a window function typically used for pulse shaping in telecommunication applications as well as for finite impulse response (FIR) filter design and spectral analysis.
- Window functions are used in applications where data is processed in short segments and have a smoothing effect by gradually tapering data values to zero at the ends of each segment.
- HammingWindow[x] is equal to
.
- HammingWindow automatically threads over lists.
