according to attached file, (page 738), the term (n-i+1) with 0<i<n+1 is for triangular window function which is a cascade of two rectangular window function.This term is used in filter section
in case we want to use higher order filter, we can use quadratic window function which consists of three rectangular windows. what is the weight expression used for quadratic (parabolic) window function (as for triangular it is Ci=(n-i+1) and for rectangular it is Ci =1)?
thanks
