In normal a.m. the sum of the power in the two sidebands can't exceed half the power of the carrier.
For example, a 100W carrier when 100% modulated will have 25W in each sideband. Since both sidebands have identical information, one of them can be considered redundant. So we are transmitting 150W and making use of only 25W.
In suppressed carrier d.s.b. we can achieve better efficiency since, with high suppression, we have 50% of the total power in each sideband.
So a 150W transmitter, at 100% modulation, will radiate 75W in each sideband.

What feature of the multiplier modules output suggests that is basically a DSBSC signal?
The feature of the multiplier module's output that suggests it is essentially a Double Sideband Suppressed Carrier (DSBSC) signal is the absence of a carrier frequency component in the output spectrum. In DSBSC modulation, the carrier wave is suppressed, and the output consists of two sidebands that carry the modulating information. This characteristic can be identified by analyzing the frequency domain representation, where only the upper and lower sidebands are present without the carrier frequency peak.
