The sidebands are not suppressed in DSB-SC ... that's where the information is !.
The carrier is suppressed, and only the sidebands are transmitted. The main
advantage of doing that is the fact that the RF power that would otherwise be
used for the carrier is then available for the sidebands. This swap typically
results in increased range of communication with the same amount of power.

What is the bandwidth of DSBSC?
BW=2 fm
How many sidebands does an FM signal generate?
2, 4, 6, 8, 10 it depends on the amount of modulation. 100%1 on each side, 200% 2 sidebands on each side.
How does double sideband differ from standard AM?
Standard AM already has double sideband. When you talk about double sideband, however, often the meaning is usually "double sideband, suppressed carrier". By suppressing the carrier, you can impute more power into the sidebands, because you are not providing power to the carrier, which accounts for a significant percentage of the total power. Since the sidebands actually contain the signal, you can boost the signal to noise ratio by suppressing the carrier. This comes at a cost, however, in complexity, because you need to regenerate the carrier in order to demodulate the signal. In fact, many systems use single sideband, suppressed carrier, doubling the available power to the sideband containing the signal over double sideband suppressed carrier. This works, again at the cost of receiver and transmitter complexity, because the two sidebands contain the same information.
What is the purpose of sidebands?
to protect information
Why is use only one sideband for the transmission of the information?
Single sideband suppressed carrier is a transmission mode that maximizes the amount of energy that the carrier uses with which to send information. In normal double sideband non-suppressed, which is standard AM broadcast style, the carrier transmits no information, and the two sidebands transmit redundant information. Suppressing the carrier is one way to put more energy into the signal. Suppressing one of the sidebands is a second stage way to do this as well. Of course, this comes with operational complexity. The receiver is more complex, but you do gain more distance because more power goes into the signal, i.e. there is no carrier and there is no redundancy.

What are three disadvantages of standard am?
1. In the spectrum of AM wave there are two sidebands and carrier. Most of the transmitted power is in the carrier. This power is wasted because the carrier contains no power, only the sidebands contain the information . 2. The standard AM systems utilize twice as much bandwidth as needed with single -sideband systems. 3. The sidebands and carrier must have precise amplitude and phase relationships. These relationships are difficult to maintain under some conditions.
How would you use suppressing in a sentence?
By taking a prescription medicine, I'm suppressing my cough. The government in Brazil has been suppressing political dissent. Suppressing his outrage at the insult, he stood and left the room.
What is a sentence for suppressing?
The suppressing of free-speech is not to be allowed in a democratic society.
What is meant by single side band modulation?
Single side band suppressed carrier modulation is like amplitude modulation except that one of the sidebands is suppressed or filtered out. Each sideband carries the same though opposite, information, so suppressing the one sideband allows more power to be placed into the one remaining sideband. The downside, of course, is that the demodulation process is more complex.
