Recurrence formula for impulse response coefficients of Sinc N FIR filter
Essam E. M. Hassan · Electronics Letters · 2006
A simple recurrence formula for computing the impulse response coefficients of the SincN FIR made of a cascade of N Sinc filters each of length M is presented. The formula allows for a much lower mathematical operation compared to the previously published format and thus leads to a faster execution time and simpler circuitry.
