Impulse response of sinc/sup N/ FIR filters
S. C. Dutta Roy · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 2006
A simple recurrence formula is presented for computing the impulse response coefficients of the sinc/sup N/ FIR filter, consisting of a cascade of N sinc filters, each of length M. A closed form expression is also given for the first M coefficients.
