What is SSB system?
In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves. A refinement of amplitude modulation, it uses transmitter power and bandwidth more efficiently.
What services use SSB?
SSB (Single Sideband) is an obscure but very important way to communicate via radio. It is used primarily for two-way voice communication by ham radio operators, aircraft and air traffic control (ATC), ships at sea, military and spy networks. Occasionally some shortwave broadcast stations use this format.
What is a SSB phone?
Single sideband is the predominant phone mode used for over-the-horizon skip propagation via the ionosphere. This article takes a closer look at the basics of SSB phone mode for better understanding of its complexities and operating nuances relative to FM channelized ops.
What is SSB receiver?
SSB receiver This generates a carrier signal that can be mixed with the incoming SSB signal, thereby enabling the required audio to be recovered in the detector. Typically the SSB detector itself uses a mixer circuit to combine the SSB modulation and the BFO signals.
Is SSB better than AM?
An SSB radio transmitter suppresses the carrier and one of the redundant sidebands, and thus transmits the operator’s voice in less than half the bandwidth of an AM signal, and with much more efficient use of energy.
Which is better SSB SC or DSBSC?
As shown in the fig-4, DSB-SC spectrum has both the sidebands and no carrier is present. Hence it needs two times the bandwidth of SSBSC as explained later. It has advantages of having lower power consumption but needs complex detection at the receiver side.
Which of the following is a disadvantage of SSB system?
| Q. | Which of the following is a disadvantage of tone-in-band SSB system? |
|---|---|
| A. | high bandwidth |
| B. | bad adjacent channel protection |
| C. | effects of multipath |
| D. | generation and reception of signal is complicated |
Why is SSB preferred over Dsbfc or DSB-SC?
The advantages of SSB-SC over DSB-FC signal are : Less bandwidth requirements . This allow more number of signals to be transmitted in the same frequency range . Lots of power saving .
