Do you understand that a DSB signal *is* AM?
So all the AM broadcasters are wasting money by
generating a carrier?
How did you jump to that conclusion.
Is "DSBSC" DSB?
There have been attempts to remove the carrier but receivers could not be
manufatured at a reasonable price that would demodulate the signal with the
fidelity of an AM BCB signal. Probably could be done today but what would
you l do with all those AM rx that suddenly dont work when the transition is
made.
