Differentiate SSB-SC and DSB-SC

To differentiate SSB-SC and DSB-SC, we need to understand their definitions and characteristics.

1. SSB-SC (Single Sideband Suppressed Carrier):

   • In SSB-SC modulation, only one sideband is transmitted, while the carrier and the other sideband are suppressed.
   • This modulation technique is used to conserve bandwidth and power.
   • SSB-SC is commonly used in applications where bandwidth efficiency is crucial, such as in long-distance communication or radio broadcasting.
   • The receiver needs a special demodulator to recover the original signal from the single sideband.

2. DSB-SC (Double Sideband Suppressed Carrier):

   • In DSB-SC modulation, both sidebands are transmitted, while the carrier is suppressed.
   • This modulation technique is used when both sidebands contain important information.
   • DSB-SC is commonly used in applications such as AM (Amplitude Modulation) radio broadcasting.
   • The receiver needs a demodulator to recover the original signal by removing the carrier and one of the sidebands.

In summary, the main difference between SSB-SC and DSB-SC lies in the number of sidebands transmitted and the carrier suppression. SSB-SC transmits only one sideband, while DSB-SC transmits both sidebands.
