One structure for fractional delay filter with small number of multipliers
Gordana Jovanović Doleček, Javier Díaz-Carmona · Electronics Letters · 2002
A wide-bandwidth, high-resolution fractional delay filter (FDF) structure with a small number of multipliers per output sample and a short coefficient computing time is presented. The proposal is based on the use of a frequency FDF design method up to only half of the Nyquist frequency, in a multirate structure.
