User:Spinningspark/Work in progress/Hourglass filter

Hourglass filters are signal processing filters designed by a method proposed by Byron J. Bennett in 1988. Bennett called these filters hourglass because the basic type (but by no means of all of them) has an associated polynomial in s whose coefficient magnitudes are symmetrical about the centre term and increase towards the end terms, suggesting an hourglass shape.^[1]
