What are the advantages and disadvantages of SSB?

What are the advantages and disadvantages of SSB?

The generation of SSB is quite complex as the suppression of one of the sidebands is difficult. The generation of SSB requires sharp cut off characteristics of the sideband suppression filter. SSB receivers require carrier recovery and synchronization circuit which adds to their cost, complexity and size.

What is the disadvantage of SSB filters?

Disadvantages. The cost of a single side band SSB receiver is higher than the double side band DSB counterpart be a ratio of about 3:1. The average radio user wants only to flip a power switch and dial a station.

What are the advantages of SSB systems?

Sideband Modulation − Advantages Bandwidth or spectrum space occupied is lesser than AM and DSB signals. Transmission of more number of signals is allowed. Power is saved. High power signal can be transmitted.

What are the disadvantages of double sideband full carrier DSB SC )?

Disadvantages of DSB-SC modulation

• It involves a complex detection process.
• Using this technique it is sometimes difficult to recover the signal at the receiver.
• It is an expensive technique when it comes to demodulation of the signal.

Is a major disadvantage of SSB system?

The disadvantage of SSB modulation are : The SSB transmitter and receiver need to have an excellent frequency stability . A slight change in frequency will hamper the quality of transmitted and received signal . Therefore, SSB is not generally used for the transmission of good quality music.

What is the main limitation of SSB SC system?

Disadvantages. The generation and detection of SSBSC wave is a complex process. The quality of the signal gets affected unless the SSB transmitter and receiver have an excellent frequency stability.

What are the disadvantages of DSB?

The disadvantages of standard Amplitude modulation or DSB-FC (Double sideband – Full Carrier ) system are as follows :

• Power wastage takes place in DSB-FC transmission.
• DSB-FC system is bandwidth inefficient system.
• AM wave gets affected due to noise.

What are the advantages and disadvantages of DSB SC modulation?

The advantage of DSB-SC modulation is its consumption of low power as obtained in overcoming the shortcomings faced by other modulation due to suppressed carrier in this modulation.

Why SSB is not used in broadcasting?

This is nearly ten times as large as the total bandwidth occupied by all the channels of the AM radio. Use of SSB modulation would cut this in half but SSB is not used for video signals because of the complexity of the SSB receivers.

Why is it difficult to achieve SSB SC transmission?

Single sideband power measurement Power measurement for an SSB signal is not as easy as it is for many other types of transmission because the actual output power is dependent upon the level of the modulating signal. To overcome this a measure known as the peak envelope power (PEP) is used.

Which of the following is a disadvantage of tone-in-band SSB system?

Which of the following is a disadvantage of tone-in-band SSB system? Explanation: Tone-in-band SSB systems has the advantage of maintaining the low bandwidth property of the SSB signals, while at the same time providing good adjacent channel protection. Explanation: FFSR stands for Feedforward signal regeneration.

What is the difference between SSB and DSB modulation?

Give advantages and disadvantages of SSB over full carrier DSB amplitude modulated wave. SSB is an amplitude modulation technique in which only one sideband (upper or lower) is transmitted and DSB is a modulation technique in which both the upper and lower sidebands are transmitted.

What is single sideband modulation?

When only one sideband is transmitted, the modulation is called as single sideband modulation . It is also known as SSB or SSB-SC modulation . Fig.1 (a) represents the spectrum X (f) of the message signal x (t) .

SSB advantages 1 As the carrier is not transmitted, this enables a 50% reduction in transmitter power level for the same level of information carrying signal. 2 As only one sideband is transmitted there is a further reduction in transmitter power. 3 As only one sideband is transmitted the receiver bandwidth can be reduced by half.

What are the limitations of SSB technology?

Implementation of SSB holds complex nature. It is expensive. SSB technique requires a transmitter and receiver to be highly frequency stable. As some slight change in frequency will deteriorate the quality of the signal. It is needed in all such applications where power saving and low bandwidth is required.
