sinc^N FIR Filter Coefficients: Closed-Form Expressions and Recursive Relations
Jean Le Bihan · 2008
SincNFIR filters resulting of a cascade of N sinc filters, each of length M, are considered. Straightforward recurrence relations are derived allowing fast computation of their impulse response coefficients. A table of coefficients is given. A simple general expression of the coefficients is also obtained, valid for all the coefficients. This latter can be easily applied for given values of M and N.
