What is analog 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)
What are the disadvantages of single sideband AM transmission?
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.
What is a transmission mode?
In radio we would have: Phone ( voice and music)- AM, FM, Citizens Band, SSB (Single side band)- then CW ( continuous wave) for code transmission, such things as Facsimile, Telex over radio ( Radio-teletype). which are entirely machine-generated like a typewriter keyboard, and so on... Television is a form of transmission mode- but is not radio but well, Video.

When was SG-SSB created?
SG-SSB was created in 1975.
What is the process of an SSB?
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.
What are the advantages of SSB and DSB over AM?
advantage of SSB ic can save power..and also the bandwidth requirements
Why does jasmine fancy ssb?
This is a lie and I don't fancy SSB, this has been a big misunderstanding !! Thanks xx
Is there such thing as ssb unleashed?
No
Institute for ssb?
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
What does ssb stand for?
ssb stands for super smash bros.
Who is your favorite ssb character?
wolf
