represents a Blackman window function of x.
- BlackmanWindow is a window function typically used 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.
- The Blackman window is a close approximation of the ExactBlackmanWindow. The truncated coefficients result in an improved high-frequency roll-off but at the cost of larger spectral side lobes.
- BlackmanWindow[x] is equal to .
- BlackmanWindow automatically threads over lists.
