Single Sideband is effectively the same as standard AM, except that the carrier and one of the two sidebands is suppressed. This allows you to put more power into the information carrying part of the signal, at the complexity of having additional circuitry on both ends to modulate and demodulate.

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.
How single sideband is being generated?
In regards to the radio transmission mode, SSB is an improvement of AM, and there are generally three ways single sideband can be generated -- filtering out the unwanted sideband and suppressing the carrier; using phasing to suppress the unwanted sideband and carrier (Hartley modulator); or quadrature mixing and filtering (Weaver modulator).

What is bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.

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.
When was Shasta sideband created?
Shasta sideband was created in 1933.
What is vestigial side band transmission?
Vestigial sideband (VSB) is a type of amplitude modulation ( AM ) technique (sometimes called VSB-AM ) that encodes data by varying the amplitude of a single carrier frequency . Portions of one of the redundant sidebands are removed to form a vestigial sideband signal - so-called because a vestige of the sideband remains.
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
What the difference between single side band single carrier transmission and full carrier AM?
1. Single-sideband transmission requires only half as much bandwidth as double sideband.2. SSBSC require less total transmitted power than full carrier AMIn full carrier AM, the transmitted signal consists of two sidebands (containing the transmitted information) and the carrier signal. Long ago, it was realized that both sidebands contained the same information, and the carrier signal could be supplied by the receiver. Thus, if you suppress transmitting the carrier and one sideband, you can use the available power to increase the power in the remaining sideband.
