Comparison between AM and SSB-SC:
AM |
SSB-SC |
In this modulation system the amplitude modulated signal contains carrier wave and 2 sidebands (upper side band and lower side band) |
The single sideband suppressed carrier contains only one sideband and no carrier is present. In this one sideband is suppressed. |
Demodulation is easy. We can use rectifier or envelope detector to demodulate conventional amplitude modulation. |
Demodulation process is difficult |
Power requirement is very high. Nearly 2/3rd of power is required to transmit this carrier wave and rest 1/3rd for the transmission of two sidebands. |
SSB-SC systems require lesser power to transmit the same information in comparison to conventional amplitude modulation (AM). |
