What are the disadvantages of single sideband AM transmission?

∙ 13y ago
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.

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).
Am single-sideband full carrier?
single sideband full carrier
Which are the applications of vestigial sideband?
Vestigial Sideband Transmission is used for the transmission of Television signals.Because the video signals need a large transmission bandwidth if transmitted using DSB-FC or DSB-SC techniques.
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.
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.

Advantages and disadvantages of envelope detection compare to synchronous detection?
One of the Advantage of synchronous detection is that it causes less distortion when compared to envelope detection. Also synchronous works well with Single sideband signals.
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 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.

Is liners legal for cb radios?
In the US at least, no, linear amps are not legal for use on CB radios. The maximum wattage permitted for AM transmission is four watts, and the maximum wattage permitted for Single Sideband is 12 watts.
