- | * //Window (Blackman Optimal): Occasionally needed when Cut 'n Window is used to shorten filters if the beginning or end of the output filter occurs at a time when the value of the input filter is significantly different from zero.

However a filter so short inevitably leads to compromises.// | + | * //Window (Blackman Optimal): |
