Thanks, This means when I send a complex signal I see it on spectrum, I too send a converted signal and I see a converted signal on the spectrum. Signals are not the same... I expect that signals in two formats (format int16 or float 32 ) be the same on a spectrum. I only have a signal in two formats...
The fact that your signal is all zeros seems to be a problem with your > signal; have you maybe scaled it incorrectly, so that it (correctly) gets > rounded to all 0? Can you explain how should I scale a float signal according to a block in Gnuradio? I don't know what "don't acceptable" would mean in this context.
