Hi guys,

Thank you all for kindely answering my question.

BTW, here's an idea I've had in mind for quire some
time, and was wondering if it's worth testing it...
I guess it's related to a 4 quadrant multiplier / ringmod...
The best I could describe it is as a coder / decoder :
a carrier is used for the coder (a sine for instance),
and another carrier is used for the decoder, but slightly
different : slightly different freq and/or phase, different
harmonic content... Could this make some "ghost harmonics"
appear in the decoded signal, a bit like on short-wave radio,
when the receiver is not 100% exactly tuned to the radio
station frequency ?

Has this been done already (and am I re-inventing the wheel
as always) or is it just crap ?

Thanks,
JB
