First, this is my first post to this interesting group and I
hope you take what I have to say constructively.
This business of SSB on AM, etc., is of interest to me
on a technical basis.
But let's do a computer simulation of this thing. To
this end I have written a computer program which
allows you to select various AM modes and the
program then shows you the transmitted envelope
and the associated spectrum.
It is temporarily posted here:
That file is just a barefoot executable without all of
the usual Window$ garbage. It should run on most
Windows computers. If not e-mail me and I'll make
a full-blown install routine.
I am suggesting you download the program and
run it. Click on the opening screen option "Single
sideband" and then click on "Ideal lower sideband".
See the transmitter output as a "carrier". Then click on
Carrier= 0 dB. Then on Carrier=-6 dB. Then on
Not real pretty, is it?
Now click on "Double sideband" and on Carrier=0 dB.
I think the folks on this group will find the routine as
interesting as others have.
