Hi Pal,
The following question about single-sideband signal confuse me for a while.

The attached files are my mathematical model.
Please help me to solve my questions and fell free to correct my analysis.

Q1, why the physical output spectrum measured by the spectrum analyzer is always symmetric and double-sideband?

Q2, how to define the channel bandwidth (bandpass) W by the analysis of
single-sideband signal x(t)? (i.e.,W=B or W=2B)

Thanks a lot.
