Hi all,
I wonder if this is a bug or what:
I just make a QPSK constellation on the unit circle with quite random data and
look at the spectrum by "QT GUI Frequency Sink" block in GRC.
With these parameters:
FFT size = 1000
Window type = None OR Rectangular
I should see a flat line as the spectrum with -30 dB (= -30 dBW) but surprisingly it
shows -33 dB !!!
I use GNU Radio Companion 3.7.13.4 and ubuntu 16.04.
Would be grateful if you could help me in this matter.
regards,
Ali
