Abstract :
The fractional interval is used to determine the interval between the output sample and the previous input sample in interpolation filters. In this paper, the effects of the quantization of this parameter are studied and the wordlength is derived for different kind of interpolation filters having anti-aliasing or anti-imaging properties.
