fractional delay filters when sampling at nyquist rate

Started by cathy zuccini December 4, 2005
Hi, I'm working on a DSP project (speech coding and synthesis) involving
fractional delay filters. I would appreciate it if you can send me matlab
codes for implementing fractional delay filters with baseband and fullband
approximation, errors between FIR filters designed using these two methods,
IIR design of FD filters as well as any other documentation about FD design
especially when sampling at Nyquist rate.

Note: I already checked the matlab codes provided by Laakso at
www.acoustics.hut.fi/software/fdtools/

Thank you..
