Which of the following is an advantage of SSB over DSB?(a) No change in spectrum space(b) Reduce in spectrum space(c) Carrier is suppressed(d) Power is not wasted on the carrierI had been asked this question in homework.The query is from Single Sideband Modulation in section Amplitude & Frequency Modulation of Avionics

Answer»

The correct answer is (b) Reduce in spectrum SPACE

To EXPLAIN I would say: In a signal, only the sidebands contain the information. Also, there is a DUPLICATION of the information in each sideband. Thus one sideband is sufficient form transmission as compared to DSB where both the sidebands are present. SINCE one of the sideband is also suppressed it reduces the maximum or the minimum FREQUENCY of the signal and hence the spectrum space is reduced in an SSB.
