represents a Blackman–Nuttall window function of x.
- BlackmanNuttallWindow 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.
- BlackmanNuttallWindow[x] is equal to .
- BlackmanNuttallWindow automatically threads over lists.

Basic Examples (3)
Create a moving average filter of length 11:
Taper the filter using a Blackman–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:
