Hi Carlos,
this might get a little too theoretical to discuss it on the mailing
list, thus I'd like to point you at the Readme [1] file referenced by
the doxygen page, as I think it explains mu as fractional delay quite
nicely.
The readme also references the book where the idea of the MMSE
interpolator will be explained in more detail.
Best regards,
Marcus

What is the exact meaning of the parameter mu?

I do not understand it :S

Hi Daniel,
because both introduce delays and the delay of one of these is 2
samples longer.
Greetings,
Marcus

Hi
I derive the output of a signal, both to an Interpolating FIR
filter and Rational Resampler (in parallel) and then I connect them
to a Time Sink (with 2 inputs). I use the same interpolation factor
for both blocks (interpolation = 4). I also use in taps the same
rcc filter. In Time Sink plot I observe a time delay in these 2
signals. Does anyone know why this happens?
Thank you Daniel
