Double-sideband suppressed-carrier transmission Totally Explained

Everything about Double-sideband Suppressed-carrier Transmission totally explained

Double-sideband suppressed-carrier transmission (DSB-SC): transmission in which (a) frequencies produced by amplitude modulation are symmetrically spaced above and below the carrier frequency and (b) the carrier level is reduced to the lowest practical level, ideally completely suppressed.
   In the double-sideband suppressed-carrier transmission (DSB-SC) modulation, unlike AM, the wave carrier isn't transmitted; thus, a great percentage of power that's dedicated to it is distributed between the sidebands, which implies an increase of the cover in DSB-SC, compared to AM, for the same power used.
   DSB-SC transmission is a special case of Double-sideband reduced carrier transmission.
   This is used for RDS (Radio Data System) due to the fact that it's difficult to decouple. Spectrum This is basically an amplitude modulation wave without the carrier therefore reducing power wastage, giving it a 50% efficiency rate. Generation DSBSC is generated by a mixer. This consists of an audio source combined with the frequency carrier.

The name "suppressed carrier" comes about because the carrier signal component is suppressed -- it doesn't appear (theoretically) in the output signal. This is apparent when the spectra of the output signal is viewed:
