Your first problem is that you're using a 32k sample rate with a 20k
sin/cos. This will actually come out as a 12k sin/cos, due to aliasing.
Try the same thing again with a 48k sample rate and see what happens.
Either bandpass filtering or a Hilbert transform can be used to create SSB.
Not sure what your flowgraph does, but it looks fun.

Hi everybody
Im trying to make SSB modulation with Hilbert transform. And Im using IQ
modulator
here is schema:

And I have a question. In Frequency domain there should be one peak, and
on on my plot there is one - that is good, and second that is
smaller/suppressed.
Is something wrong ?? or is it normal ??
Is Hilbert method for creating SSB signal is good ?? or can it be made
easier ???
thank you very much.
