Hi all, I played a bit with the example "E2.3. A Note on Resampling" provided in the GNURadio tutorial [1].
My question is about the changes in the signal's amplitude value after it is interpolated. For a interp. factors of 16 and 32, for instance, I observed gains of about 1 dB and 5 dB, respectively, in comparison to the "normal" signal. Could someone share some thoughts about this? Is this consistent with theory? Thanks in advance.
