Sr. Dooley et Ak. Nandi, Notes on the interpolation of discrete periodic signals using sinc function related approaches, IEEE SIGNAL, 48(4), 2000, pp. 1201-1203
Considering the sinc interpolation of discrete periodic signals, this corre
spondence establishes the equivalence of two recently published methods. Fu
rthermore, the interpolation methods are equivalent to a fractional delay f
ilter designed using the frequency sampling technique. A numerically stable
and computationally attractive form of the equivalent methods is presented
.
