| Abstract: | A closed form solution for the approximation of a linear-phase FIR (finite impulse response) filter with equiripple magnitude responsein the passband and stopband was not known. In this letter we present a closed form solution of some equiripple linear-phase half-band FIR filter approximation. |
| Keywords: | Optimal FIR filter Linear-phase Half-band filter |
