The advantages of DSB-SC are that power consumption is nominal, the power from the signal can be contained in four sidebands, and the bandwidth is double the amount in the signal.
Advantages-
low bandwidth requirement
power saving
less effected by noise
disadvantage-
Complex modulation and demodulation circuitry
a bit expansive in comparison to DSB

The Possibility exists this is a science-fiction device akin to the Sub-Space radio used on The televisin program Star Trek. The device (Neutroni ) was something akin to a long range but somewhat clandestine (SSB?) radiophone system. the device was(More than Plausible)
Am- DSB stands for Double or Duplex Side Band Am- SSB- amplitude modulation, which is what Am means, Single-Side-Band, sideband sometimes written as one word but abbreviated phonetically as SSB. SSb is widely used in amateur radio and some forms of CB as well. the concept is related to the much older, and still viable idea of Bandspreading, or Bandspread where the tuning is split over two dials or a subdial for the fine-tuning harmonics. applied to receivers only. Get some old electronics magazines from the thirties from Lindsay"s publications, angled at the hobbyist they explain things as they go along. the Gernsback l934 Short wave manual is good technical theory and also has reviews and circuit diagrams of many then current radio gear, great fun for browsing.=and technically correct. ********************************************************** Normal a.m. transmission has a carrier and two identical sidebands, the upper and lower. That's a.m. d.s.b. (double sideband). The sum of the power in the two sidebands can't exceed half that of the carrier. For example, a 100W carrier modulated to 100% will have 25W in each sideband. It is possible to achive better efficiency by suppressing the carrier, which means that half the transmitted power will be in each sideband. That's still d.s.b., with the addition of s.c. to indicate the difference. A further increase in efficiency can be achived by also suppressing one of the sidebands, so all of the transmitted power is in that sideband. That is what is normally referred to as s.s.b., but more correctly it's s.s.b. s.c.
in SSB-SC only one side band of AM s/g is sent frm Transmitter instead of both sideband and carrier in that of DSB-FC(DSB-FC consist of upper side band ,lower side band both conveying same information i.e. mirror image of each other and original carrier i.e. after the process of modeulation carrier is also present in DSF-FC s/g). thus DSB-FC = USB+LSB+Cariier hence total power in DSB-FC= cariier pow+ usb pow+lsb pow SSB-SC = either USB or lsb toatal pow= pow in single side band 1.using SSB-Sc power is saved. 2.Bandwith is reduced 3. noise immunity is more.

An AM transmission, viewed on a spectrum analyser, has a carrier and two sidebands. AM transmissions are easy to generate, transmit and receive. This is the advantage of AM. AM is widely used for broadcast radio stations below 30MHz. If a very high quality filter is used, the carrier and one sideband can be removed from an AM transmission. This is called single sideband (SSB). The main advantage of SSB is that it occupies less than half the spectrum space of an AM transmission so more than double the number of transmissions can fit into a given frequency band. This is the advantage of SSB. SSB is used by ships, aircraft and radio amateurs. To receive SSB, the carrier has to be recreated in the receiver on exactly the right frequency. This makes SSB transmissions tricky to tune in. SSB has the nick name of "Donald Duck" because this is what it sounds like if the receiver tuning is not quite right. Also music is very difficult to tune in. This is the main disadvantage of SSB.
An advantage of a single side band (SSB) is that it only needs half the bandwidth of AM. AM stands for amplitude modulation.
Analog modulationIn analog modulation, the modulation is applied continuously in response to the analog information signal.Common analog modulation techniques are:Amplitude modulation (AM) (here the amplitude of the modulated signal is varied) Double-sideband modulation (DSB) Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)Double-sideband suppressed-carrier transmission (DSB-SC)Double-sideband reduced carrier transmission (DSB-RC)Single-sideband modulation (SSB, or SSB-AM), SSB with carrier (SSB-WC)SSB suppressed carrier modulation (SSB-SC)Vestigial sideband modulation (VSB, or VSB-AM)Quadrature amplitude modulation (QAM)Angle modulation Frequency modulation (FM) (here the frequency of the modulated signal is varied)Phase modulation (PM) (here the phase shift of the modulated signal is varied)
SG-SSB was created in 1975.
SSB stands for Services Selection Board. The SSB is a test for Armed Forces of India. The process of an SSB would be that they test your intelligence and personality in 5 days to check compatibility and a persons potential.
This is a lie and I don't fancy SSB, this has been a big misunderstanding !! Thanks xx
No
I think there are a lot of materials on web teaching you the preparations required for SSB's but i suggest you read the below Blog. As its written by a recommended candidate. BLOG : http://vscribe.blogspot.com Good luck for your ssb
ssb stands for super smash bros.
