represents a Nuttall window function of x.
- NuttallWindow is a window function typically used in signal processing applications where data needs to be processed in short segments.
- Window functions have a smoothing effect by gradually tapering data values to zero at the ends of each segment.
- NuttallWindow[x] is equal to .
- NuttallWindow automatically threads over lists.

Create a moving-average filter of length 21:
Taper the filter using a Nuttall window:
Log-magnitude plot of the power spectra of the filters:
Use a window specification to calculate sample PowerSpectralDensity:
Compare to spectral density calculated without a windowing function:
The plot shows that window smooths the spectral density:
Compare to the theoretical spectral density of the process:
Use a window specification for time series estimation:
