I think you are confused because you're doing the math on paper with
real sin/cos functions. The complex signal sources produce complex
oscillations ($s_f(t)=e^{j2\pi f t}$), which do not have symmetrical
spectrum.
Do the math with the exponential function; it get's easier than what you
have to do
Can you plz explain Martin or give me a link atleast...thnx in advance

That is actually the mathematically correct thing
When we multiply two complex signals in GNU Radio companion and see the
result using WX FFT block then there is no frequency difference
component(f1-f2) but only the addition component(f1+f2)...why is that??
